Use of undefined constant photo - assumed 'photo' - php

I am having two problems, one of them odd and the other confusing.
Firstly I have basically the same code in two pages and in one page it works and in the other it comes up with an error.
echo "<td style='width: 800px'>" . '<img height="100" width="100" src="data:image/jpeg;base64,'.base64_encode( $row[photo] ).'" >' . "</td>";
This comes up with the error Use of undefined constant photo - assumed 'photo'.
Which to me means syntax error but for the life of me I cannot work out what needs to be done.php/html syntax can absolutely baffle the hell out of me.
The second problem is just an odd problem.
a:link {
color: black;
}
Links are black.
a:hover {
color: #4cff00 ;
}
links turn green when the mouse is hovered on them.
a:visited {
color:black;
}
Links are no longer green when hovered over but instead are always black. I would like them to be green when hovered over but black at every other time, I cannot seem to get this.

Use $row["photo"] for your first problem. Add quotes or double quetes around your key photo, because if not, php parse as a constant.
For your css problem:
a:link, a:active, a:visited {color: #000}
a:hover {color: #4cff00;}
You need to set all other cases to black with pesudo codes.

try with -
base64_encode( $row["photo"] );

Rows color on report doesn't show up on print out/preview [duplicate]

I am trying to print a page. In that page I have given a table a background color.
When I view the print preview in chrome its not taking on the background color property...
So I tried this property:
-webkit-print-color-adjust: exact;
but still its not showing the color.
http://jsfiddle.net/TbrtD/
.vendorListHeading {
background-color: #1a4567;
color: white;
-webkit-print-color-adjust: exact;
}
<div class="bs-docs-example" id="soTable" style="padding-top: 10px;">

The CSS property print-color-adjust: exact; works appropriately.
However, making sure you have the correct CSS for printing can often be tricky. Several things can be done to avoid the difficulties you are having. First, separate all your print CSS from your screen CSS. This is done via the #media print and #media screen.
Often times just setting up some extra #media print CSS is not enough because you still have all your other CSS included when printing as well. In these cases you just need to be aware of CSS specificity as the print rules don't automatically win against non-print CSS rules.
In your case, the print-color-adjust: exact is working. However, your background-color and color definitions are being beaten out by other CSS with higher specificity.
While I do not endorse using !important in nearly any circumstance, the following definitions work properly and expose the problem:
#media print {
tr.vendorListHeading {
background-color: #1a4567 !important;
print-color-adjust: exact;
}
}
#media print {
.vendorListHeading th {
color: white !important;
}
}
Here is the fiddle (and embedded for ease of print previewing).
That CSS property is all you need it works for me...When previewing in Chrome you have the option to see it BW and Color(Color: Options- Color or Black and white) so if you don't have that option, then I suggest to grab this Chrome extension and make your life easier:
https://chrome.google.com/webstore/detail/print-background-colors/gjecpgdgnlanljjdacjdeadjkocnnamk?hl=en
The site you added on fiddle needs this in your media print css (you have it just need to add it...
media print CSS in the body:
#media print {
body {-webkit-print-color-adjust: exact;}
}
UPDATE
OK so your issue is bootstrap.css...it has a media print css as well as you do....you remove that and that should give you color....you need to either do your own or stick with bootstraps print css.
When I click print on this I see color....
http://jsfiddle.net/rajkumart08/TbrtD/1/embedded/result/
Chrome will not render background-color, or several other styles, when printing if the background graphics setting is turned off.
This has nothing to do with css, #media, or specificity. You can probably hack your way around it, but the easiest way to get chrome to show the background-color and other graphics is to properly check this checkbox under More Settings.
I just needed to add the !important attribute onto the the background-color tag in order for it to show up, did not need the webkit part:
background-color: #f5f5f5 !important;
Your CSS must be like this:
#media print {
body {
-webkit-print-color-adjust: exact;
}
}
.vendorListHeading th {
background-color: #1a4567 !important;
color: white !important;
}
FOR THOSE USING BOOTSTRAP.CSS, this is the fix!
I have tried all the solutions and they weren't working... until I discovered that bootstrap.css had a super annoying #media print that resets all your colors, background-colors, shadows, etc...
#media print{*,:after,:before{color:#000!important;text-shadow:none!important;background:0 0!important;-webkit-box-shadow:none!important;box-shadow:none!important}
So either remove this section from bootstrap.css (or bootstrap.min.css)
Or override these values in the css of the page you want to print in your own #media print
#media print {
body {
-webkit-print-color-adjust: exact;
}
.customClass{
//customCss + !important;
}
//more of your custom css
}
For IE
If you are using IE then go to print preview ( right click on document -> print preview ), go to settings and there is option "print background color and images", select that option and try.
If you are using bootstrap or any other 3rd party CSS, make sure you specify the media screen only on it, so you have the control of the print media type in your own CSS files:
<link rel="stylesheet" media="screen" href="">
if you are using Bootstrap.just use this code in your custom css file. Bootstrap removes all your colors in print preview.
#media print{
.box-text {
font-size: 27px !important;
color: blue !important;
-webkit-print-color-adjust: exact !important;
}
}
Are your sure this is a css issue ? There are some posts on google around this issue:
http://productforums.google.com/forum/#!category-topic/chrome/discuss-chrome/eMlLBcKqd2s
It may be related to the print process. On safari, which is webkit also, there is a checkbox to print background images and colors in the printer dialog.
Use the following in your #media print style sheet.
h1 {
background-color:#404040;
background-image:url("img/404040.png");
background-repeat:repeat;
box-shadow: inset 0 0 0 1000px #404040;
border:30px solid #404040;
height:0;
width:100%;
color:#FFFFFF !important;
margin:0 -20px;
line-height:0px;
}
Here are a couple things to note:
background-color is the absolute fallback and is there for posterity mostly.
background-image uses a 1px x 1px pixel of #404040 made into a PNG. If the user has images enabled it may work, if not...
Set the box-shadow, if that doesn't work...
Border = 1/2 your desired height and/or width of box, solid, color. In the example above I wanted a 60px height box.
Zero out the heigh/width depending on what you're controlling in the border attribute.
Font color will default to black unless you use !important
Set line-height to 0 to fix for the box not having physical dimension.
Make and host your own PNGs :-)
If the text in the block needs to wrap, put it in a div and position the div using position:relative; and remove line-height.
See my fiddle for a more detailed demonstration.
There's a style in the bootstrap css files under #media print{*,:after,:before ....} that has color and background styles labeled !important, which remove any background colors on any elements. Kill those two pieces of css and it will work.
Bootstrap is making the executing decision that you should never have any background color in prints, so you have to edit their css or have another !important style that is a higher precedence. Good job bootstrap...
I used purgatory101's answer but had trouble keeping all colours (icons, backgrounds, text colours etc...), especially that CSS stylesheets cannot be used with libraries which dynamically change DOM element's colours. Therefore here is a script that changes element's styles (background-colour and colour) before printing and clears styles once printing is done. It is useful to avoid writing a lot of CSS in a #media print stylesheet as it works whatever the page structure.
There is a part of the script that is specially made to keep FontAwesome icons color (or any element that uses a :before selector to insert coloured content).
JSFiddle showing the script in action
Compatibility: works in Chrome, I did not test other browsers.
function setColors(selector) {
var elements = $(selector);
for (var i = 0; i < elements.length; i++) {
var eltBackground = $(elements[i]).css('background-color');
var eltColor = $(elements[i]).css('color');
var elementStyle = elements[i].style;
if (eltBackground) {
elementStyle.oldBackgroundColor = {
value: elementStyle.backgroundColor,
importance: elementStyle.getPropertyPriority('background-color'),
};
elementStyle.setProperty('background-color', eltBackground, 'important');
}
if (eltColor) {
elementStyle.oldColor = {
value: elementStyle.color,
importance: elementStyle.getPropertyPriority('color'),
};
elementStyle.setProperty('color', eltColor, 'important');
}
}
}
function resetColors(selector) {
var elements = $(selector);
for (var i = 0; i < elements.length; i++) {
var elementStyle = elements[i].style;
if (elementStyle.oldBackgroundColor) {
elementStyle.setProperty('background-color', elementStyle.oldBackgroundColor.value, elementStyle.oldBackgroundColor.importance);
delete elementStyle.oldBackgroundColor;
} else {
elementStyle.setProperty('background-color', '', '');
}
if (elementStyle.oldColor) {
elementStyle.setProperty('color', elementStyle.oldColor.value, elementStyle.oldColor.importance);
delete elementStyle.oldColor;
} else {
elementStyle.setProperty('color', '', '');
}
}
}
function setIconColors(icons) {
var css = '';
$(icons).each(function (k, elt) {
var selector = $(elt)
.parents()
.map(function () { return this.tagName; })
.get()
.reverse()
.concat([this.nodeName])
.join('>');
var id = $(elt).attr('id');
if (id) {
selector += '#' + id;
}
var classNames = $(elt).attr('class');
if (classNames) {
selector += '.' + $.trim(classNames).replace(/\s/gi, '.');
}
css += selector + ':before { color: ' + $(elt).css('color') + ' !important; }';
});
$('head').append('<style id="print-icons-style">' + css + '</style>');
}
function resetIconColors() {
$('#print-icons-style').remove();
}
And then modify the window.print function to make it set the styles before printing and resetting them after.
window._originalPrint = window.print;
window.print = function() {
setColors('body *');
setIconColors('body .fa');
window._originalPrint();
setTimeout(function () {
resetColors('body *');
resetIconColors();
}, 100);
}
The part that finds icons paths to create CSS for :before elements is a copy from this SO answer
I tried all suggested solutions here (and in many other questions), such as applied background-color: #000 !important; both in stylesheet and inline, or set
#media print {
* {
color-adjust: exact !important;
-webkit-print-color-adjust: exact !important;
print-color-adjust: exact !important;
}
}
, even combined them together, but nothing worked.
After hours of researching without any results, I recognized that the "bug" lost background-color only appears on table (th, td), but other HTML elements (div,...) or other CSS attributes (border-color,...) still work.
Therefore, I came up with a "hack" to wrap-up anything inside <th> or <td> with a <div> (you can adjust padding to make it display same as prior).
Here I used React and makeStyles of #material-ui/core.
JSX:
<Table bordered>
<thead className={classes.thead}>
<tr>
<th><div>Col 1</div></th>
<th><div>Col 2</div></th>
<th><div>Col 3</div></th>
</tr>
</thead>
<tbody>
<tr>
<td className={classes.tdGreen}><div>Row 1 - Col 1</div></td>
<td><div>Row 1 - Col 2</div></td>
<td><div>Row 1 - Col 3</div></td>
</tr>
<tr>
<td><div>Row 2 - Col 1</div></td>
<td className={classes.tdBlue}><div>Row 2 - Col 2</div></td>
<td><div>Row 2 - Col 3</div></td>
</tr>
</tbody>
</Table>
Styles:
const useStyles = makeStyles(() => ({
thead: {
textAlign: 'center',
'& th:not(:last-child)': {
padding: '0',
'& > div': {
padding: '.75rem',
backgroundColor: '#D8D8D8 !important',
}
}
},
tdGreen: {
padding: '0 !important',
'& > div': {
padding: '.75rem',
color: 'white',
backgroundColor: 'green !important',
}
},
tdBlue: {
padding: '0 !important',
'& > div': {
padding: '.75rem',
color: 'white',
backgroundColor: 'blue !important',
}
}
}));
You can take the idea and convert it into pure HTML/CSS solutions.
Hope this can help anyone struggled with this issue!
You can also use the box-shadow property.
The best solution for this if you are using bootstrap so just do one thing remove #media print {} all code inside this. and enable background graphics from more settings while taking print preview.
You can use inline css styles with !important.
Eg.
<p style="background:red!important">ABCD</p>
If you are using nextjs or react add this to the global css:
#media print {
body {
-webkit-print-color-adjust: exact;
}
}
This worked for me.
you can download bootstrap 4 css from bootstrap web and looking on the bottom code
look where code is
and remove this css style because this override your css color table style
If you download Bootstrap without the "Print media styles" option, you will not have this problem and do not have to remove the "#media print" code manually in your bootstrap.css file.
I double load my external css source file and change the media="screen" to media="print" and all the borders for my table were shown
Try this :
<link rel="stylesheet" media="print" href="bootstrap.css" />
<link rel="stylesheet" media="screen" href="bootstrap.css" />

why are my divs showing in wrong place

I am showing 5 results on a html page using divs and absolute position. I have used display:table-cell; and display:flex; for center positioning of image and text.
What i have problem is with for some reason after creating a parent div for each result, giving it a border, for some reason eben though i use absolute position there seems to be some uniform space between results. I see the borders in the right place, but the result contents are shown out of place.
See here:
https://www.dropbox.com/s/deeycdr32ejcftd/proferror.jpg?dl=0
Something is spacing out the results wringly. When I take out the parent container labelled profile[1 to 6] then it does work.
heres the php which is echoing the HTML:
echo "<div id='results' style='position:absolute;left:0px;top:0px;'>"
(while loop)
echo "<div id='profile".$profileid."' style='border-style: solid;position:absolute;left:0px;top:".$yy."px;width:320px;height:50px;'>";
echo "<div id='pic".$profileid."' style='display:table-cell; vertical-align:middle; text-align:center;background-color: #434345;position:absolute;left:0px;top:".$yy."px;width:50px;height:50px;overflow: hidden;'>";
echo "<a href='http://rafnet.co.uk/click/php/requests.php?from=".$username."&to=".$row["username"]."'><img style='max-height: 100%;' src='http://rafnet.co.uk/click/images/".$row["image"]."' /></a></div>";
echo "<div style='color:#0d00ff;display:flex; align-items: center; justify-content: center;position:absolute;left:50px;top:".$yy."px;width:270px;height:30px;overflow: hidden;'>".$name."</div>";
echo "<div style='display:table-cell; vertical-align:middle; text-align:center;position:absolute;left:50px;top:".($yy+30)."px;width:270px;height:20px;overflow: hidden;'>".$info."</div></div>";
$yy+=60;$profileid+=1;
(end of while loop)
echo "</div>"
echo "<div style='display:table-cell; vertical-align:middle; text-align:center;position:absolute;left:50px;top:".($yy+30)."px;width:270px;height:20px;overflow: hidden;'>".$info."</div></div>";
Try taking away the second </div> at the end of this line
I managed to fix this issue. What I realised after some work was that all the divs inside the parent div "profile" were being positioned relative to its position.
so for those divs i changed
top:".$yy."px;
to
top:0px;
ref to css are you saying i shoudlnt use the style attribute to define things? Are you saying i should place the css in the head section and assign them using the id or class? I just using the style attribute as i can see without referencing to what element it applies to

For every other output in php

So I have a $res
$res = $conn->query("SELECT username, Hours,joined FROM users ORDER by Hours DESC LIMIT 10");
which leads to this table:
while ($row =$res->fetch_assoc()){
echo "<tr><td>" .$row["username"] ."</td><td>"
. $row["Hours"]."</td><td>".$row["joined"]."</td></tr>";
}
Then using html and css:
table, td, th {
background-color:#F2F2F2;
font-size:20px;
left:20px;
th {
background-color: green;
color: white;
}
How do I make the first output a certain color, which in this case would be #F2F2F2(light gray) background. Then a second output(column) a white background color? Then third output #F2F2F2 again, so it's basically every other time. I am thinking about an if statement? but couldn't exactly think of a specific one. So far I am getting, as planned, a ugly pure gray back grounded table.
There is a cleaner way to do it with CSS3 you can do this without using php using the nth_child() selector like this
table, td, th {
background-color:#F2F2F2;
font-size:20px;
left:20px;
th {
background-color: green;
color: white;
}
tr:nth-child(even) {
background-color:#fff
}
In your case this makes all the even table rows i.e 2,4,6.... have a background color of white, you can also change the argument even to odd, depending on how you want to use it. It should also be noted that Internet Explorer 8 and earlier versions do not support the :nth-child() selector
This is a quick and dirty way:
$i=0;
while ($row =$res->fetch_assoc()){
$bg="";
if ($i & 1) $bg=' bgcolor="#f2f2f2"';
echo "<tr$bg><td>" .$row["username"] ."</td><td>"
. $row["Hours"]."</td><td>".$row["joined"]."</td></tr>";
$i++;
}

Overlapping relatively positioned objects after a jQuery function

So I've looked around quite a bit for an example to this but I couldn't find anything for what exactly I am trying to do.
I'm building a blog with the front page having a bunch of posts in order like this -
http://prntscr.com/1vjoun
The blogs vary in size based on how much text is in them -
http://prntscr.com/1vjozq
When you hover over a blog I am trying to make a small bar appear inside of the blog that overlaps the text at the bottom so that I can have some options appear, such as 'Like' 'Favorite' 'Feature' or w/e and this is where my problem comes in.
echo "<div class='blogpost' id='" . $row['blogid'] . "'>";
echo "<h3 class='blogheader'>" . $row['blogheader'] . "</h3>";
echo "<p class='blogbody'>" . $row['blogbody'] . "</p>";
echo "<div class='blogextras'></div>";
echo "</div>";
I create the 'blogextras' div that will hold the options mentioned above.
.blogextras {
position:relative;
height:35px;
width:100%;
background:#333;
}
I give it some style.
$(".blogpost").hover(function(){
$(".blogpost").css("overflow", "auto");
$(".blogextras").show();
$(".blogextras").css("position", "absolute");
});
$(".blogpost").mouseleave(function(){
$(".blogpost").css("overflow", "hidden");
$(".blogextras").hide();
$(".blogextras").css("position", "relative");
});
Add some jQuery.
But my final result makes the 'blogextras' div appear below where I want it to be (about 35 pixels) -
http://prntscr.com/1vjppq
I also tried not changing it's position from relative to absolute and this does give a kind of desired result except it makes the boxes re-size which I don't want it to do.
I want the 'blogextras' div to appear at the bottom of the visible text area every time no matter the size of the 'blogpost' div.
Sorry if I haven't been discriptive enough or haven't given enough code just post a comment if you want to see more.
Your .blogpost container needs a relative position so that you can position your .blogextras bar exactly within that container. You also need to give the .blogextras bar a higher z-index so that it overlaps the .blogpost content:
.blogpost {
position:relative;
overflow:hidden;
/* Other CSS */
}
.blogextras {
position:absolute;
z-index:10;
bottom:0;
left:0;
display:none;
height:35px;
width:100%;
background:#333;
}
$(".blogpost").hover(function(){
$(".blogextras").fadeIn();
});
$(".blogpost").mouseleave(function(){
$(".blogextras").fadeOut();
});
Untested, but that should give you ~ what you need.

CSS inside my PHP file

Okay, so I've been able to define the standard text color according to a database value by using this code:
<?php
echo '<div style="color: ' . $result->properties->fcolor . ';';<br />
echo 'background: ' . $result->properties->bgcolor;<br />
echo '">MY CONTENT</div>'
?>
The color that's set by
$results->properties->fcolor
works nicely, except for a:link, a:hover, a:visited, and a:active. Because it's only defining "color", the browsers default to their own link colors.
My users choose from a selection of background and font colors and Chrome's default blue link color doesn't exactly work with a dark purple background... Is it possible to set up a
<style type=text/css>
inside of my PHP file and have it reference the
$result->properties->fcolor
value that the normal part of the script pulls from my database?
This is my first big site so I'm not positive about anything but I vaguely remember enabling PHP in my external CSS file using .htaccess and it didn't successfully pull in the value of
$result->properties->fcolor
as far as I could tell.
What am I doing wrong?
Thanks in advance - amazing community here! :)
IF I'm you, I would create external css for links just to define rules not color.
for example if your links are inside div, what you can do is just define to use color of div
div a { color: inherit; }
div a:HOVER { color: inherit; }
so when you define your color to div through php logic your links inside div will inherit that color.
If you experience any problems with this add important to property so color of div will be used
div a {color: inherit !important; }
YOu can set you link colors via internal css
<style type="text/css">
a:link { color:#f00;}
a:visited { color : }
a:hover {}
a:active { }
</style>
Note:
1 orders are very important .
2 use hex value instead of color name.
Hi have you tried using " instead of ' and \" instead of "?
echo "<div style=\"color: " . $result->properties->fcolor . ";";
echo "background: " . $result->properties->bgcolor;
echo "\">MY CONTENT</div>";
And, you seem to be missing a semi colon at your 3rd echo.
