I hope its not duplicate or already been answered because I cant find nothing similar on SO.
I have included file: include 'data/news.php';
<?php
$news = '
<div class="news_title">News Title</div>
<div class="news_date">Newsdate</div>
<div class="news_content">News content</div>
';
echo $news;
?>
In index file I try to show $news like this:
<div class="rightbox"><div class="h1title">Novice</div>
<?php $news ?>
</div>
Class "rightbox" is floated to the right side, but my $news is displayed right after menu content, its not in < div class =" rightbox " > "here" < /div > as I thought it should be (it makes no sense -> it should be in rightbox div but its not ??
Here's a screenshot of firebug:

I cant find any explanation on this so any suggestions would be welcome.
echo <-- you need to echo the variable.
Simply writing the variable name in the php does nothing. You need to print the contents of the variable to the page.
Two possible ways of doing this are:
1.echo
echo $news;
2. print
print $news;
They both to the same thing.

I have a wordpress function that displays adverts every so often. When are not shown essentially I would prefer to the div to display:none;
I can not seem to figure out the correct PHP function in order for the div not to display when a advert is uploaded.
<div class="advert" <?php if(!empty($_GET['details'])) {echo "style='display: none'";} ?>></div>
Why not completely not echo "advert" element?
if ( !empty($_GET['details']) ){
echo '<div class="advert">add text</div>';
}
if you really want to just hide, you can assign hide class
<div class="advert <?php echo ( empty($_GET['details'])? 'hide' : '' );">add text</div>
then you would need to add "hide" class with display:none in your style.css
Above is shorthand/ternary if/else statement used, its great if you need output some string.
And, please don't output/trust any user input i.e. $_GET['details'] 'as is' anywhere without escaping it, for security reasons.
Wordpress have plenty easy-to-use escape functions, like esc_attr() and esc_html().
This should do it for you
<?php
$advert_display_string = "";
if (!isset($_GET['details'])) {
$advert_display_string = "style='display: none'";
}
?>
<div class="advert" <?php echo $advert_display_string ; ?> ></div>`
but having said that, instead of displaying it and then hiding it with css, you could just choose only to display it if you need it there, like below
<?php
if (isset($_GET['details'])) {
?>
<div class="advert"></div>
<?
}
?>
I have this website were you can order products.
The title of the products you can order are in HTML:
<div class="whatever"> Title </div>
I want to retrieve this "title" and set my php variable $product to the value "Title".
I have search a lot on the internet but somehow I am not able to find my answer.
How can I do it?
You can use \DOMDocument->loadHTML();
Ex:
<?php
$doc = new \DomDocument();
$doc->loadHTML('<div class="whatever"> Title </div>');
View examples here:
http://docs.php.net/manual/en/domdocument.loadhtml.php
This is assuming that your source is available to php. It would probably be more pragmatic to extract the value with javascript in the client and send it with the page request. If your app is well structured, the logic that renders the title into the page in the first place is probably where you should be looking to retrieve the information rather than trying to parse the html separately.
If you mean that you would like to do this from the client side, you should be using AJAX to achieve this. However, I think you mean that you want to put the HTML in a variable. That is very simple:
$variable = "<div class=\"whatever\"> Title </div>";
And to output the HTML:
echo $variable;
You can also add multiple elements to a single variable by concatting.
$variable = "";
$variable .= "<div class=\"whatever\"> Title </div>";
$variable .= "<div class=\"whatever\"> Another Title </div>";
echo $variable;
If you mean that you want to echo a variable within a dv, that works exactly the same way:
<div class="title"><?php echo $product; ?></div>
Or better looking:
<div class="title"><?= $product; ?></div>
I have my data being output to a span currently... this is how it looks:
Now, when i remove the span and place a div there i am given this output:
This is desired, but I want to set a height to my page and have the data show up in as little as 3 columns. How would I do this? I have searched everywhere online but can't seem to find anything that shows a solution.
I did read that some use javascript for the format but i am still clueless on even this option.
My desired output would look like this:
If you know how many items you want in a column then you can seperate them out into individual divs and then float those divs to the left to get them to be next to each other.
<div style='float:left'>
//Items go here
</div>
<div style='float:left'>
//Items go here
</div>
etc.
If you figure out how many items your query returned, say using mysql_num_rows() and divide by 3 you can tell how many to put in each column.
Also be sure to clear the floats afterwards, so like this:
<div style="clear:both"></div>
Sometimes this is necessary as there will be random issues if this is not put there.
What you are describing can be solved with styling only. You have several divs that must be displayed in columns. The easiest way is floating them to the left, and setting the width for 1/3 of the parent. If you want 4 columns, set the with to 1/4 of the parent, and so on.
<div class='sqlResult' style="float:left;width:33%;">
<a href='#'>$key</a>
</div>
Also as other answers mentioned, don't use duplicated ids. Always use classes. If you need to target each div individually, give it a unique id, such as "category_1", "category_2", and so on.
This should work
<table><tr>
<?php $count=0; $total=mysqli_stmt_num_rows($sql)-1; $idxcount=0; $limit=10; while($row = mysqli_fetch_array($sql)): $key = $row['Keyword_Name']; ?>
<?php if($count == 0){ echo '<td>';} ?>
<span>
<?php echo $key; ?>
</span>
<?php if($total == $idxcount): ?>
</td>
<?php elseif($count == $limit): ?>
</td>
<?php $count=0; else: $count++; ?>
<?php endif; $idxcount++; ?>
<?php endwhile; ?>
</tr></table>
In PHP i'm using the following code to put a banner at the top of my website.
$eventinfo = simplexml_load_file("eventinfo.xml");
<div id="eventinfo"><?php foreach($eventinfo->children() as $child){ $final = $child["name"]."...<a href='".$child["adr"]."'>more info...</a>"; } ?>
</div>
The XML doc is available at the following: http://eastsidespeedway.raceresults.co/eventinfo.xml
If you go to http://eastsidespeedway.raceresults.co/index.php you'll see that the more info... link is showing up twice. One with the correct link, and the other with a link to the same page (index.php).
Can anyone shed some light on what I'm doing wrong?
Also. If you see anything that I'm doing wrong, or you know something that's easier - let me know! This is my first time using XML/PHP so I'm kinda just wingin it. Haha.
this will work for you
<?php
$doc = new DOMDocument();
$doc->load('http://eastsidespeedway.raceresults.co/eventinfo.xml');
$title = $doc->getElementsByTagName('title');
$link = $doc->getElementsByTagName('link');
//print_r($eventinfo);
?>
<div id="eventinfo">
<?php echo $title->item(0)->getAttribute('name'); ?>
<a href='<?php echo $link->item(0)->getAttribute('adr'); ?>'>More Infoo..</a>
</div>
If you look at your source:
<div id="eventinfo">5/18/2013 - Al Smiley Memorial...<a href=''>more
info...</a>...<a href='http://www.eastsidespeedway.com/dirt.html'>more
info...</a></div>
You've got two hyperlinks- one href is blank meaning that it will redirect to the current page, check your HTML code first to see if you've accidentally duplicated the element, otherwise look at the construction of your string in the php code
What I'm trying to do is to add some HTML tags to my Joomla! module titles. I will need something like this
Some <b>Title</b>
but when I save !Joomla trims the titles and remove all HTML tags.
I've check the administrator/com_content, which I think should be responsible for inserting the database data, but I couldn't find the answer there.
Can anyone help me with this headache?
Check out ../templates/system/html/modules.php
You can style your module structure in HTML.
function modChrome_myCustomModule($module, &$params, &$attribs)
{
$doc =& JFactory::getDocument();
$css = ".otherClass {}";
$css .= ".yourClass {}";
$doc->addStyleDeclaration($css);
?>
<div>
<?php if ($module->showtitle != 0) : ?>
<h1><?php echo $module->title; ?></h1>
<?php endif; ?> // post your title
</div>
<div>
<?php echo $module->content; ?> // post your module content
</div>
<?php
}
Then call your styled module in index.php:
<jdoc:include type="modules" name="right" style="myCustomModule" />
So I found the solutions. It includes both of the previous answers, so I'm putting a new one here with the correct code.
First of all I need to say, that this solution works only for a fixed amount of words (last one, two, etc.) I need only to have the last one, so I will post an example code with one word.
First as SMacFadyen sad I needed to create a new module structure in my template html folder: /templates/system/html/modules.php file.
Note: If you don't want to add this new module styling to all templates, but just on one of them you need to put the module.php in your template's html folder.
The provided by SMacFadyen looks like this:
function modChrome_myCustomModule($module, &$params, &$attribs)
{
$doc =& JFactory::getDocument();
$css = ".otherClass {}";
$css .= ".yourClass {}";
$doc->addStyleDeclaration($css);
?>
<div>
<?php if ($module->showtitle != 0) : ?>
<h1><?php echo $module->title; ?></h1>
<?php endif; ?> // post your title
</div>
<div>
<?php echo $module->content; ?> // post your module content
</div>
<?php
}
Then expired by the comments of Hanny I've added some php code to match the last word of the title and to store it in a new varibale.The code looks like this:
$wrap_tag = 'b';
$html_title = preg_replace("~\W\w+\s*$~", '<'.$wrap_tag.'>'.'\\0'.'</'.$wrap_tag.'>', $module->title);
Note: the $wrap_tag variable stores the tag you want. You can put b, em, u and etc. to have different result.
The last thing was to replace the displayed title, so I've replaced this code:
<h1><?php echo $module->title; ?></h1>
with this one:
<h1><?php echo $html_title; ?></h1>
The final result was this:
function modChrome_myCustomModule($module, &$params, &$attribs)
{
$doc =& JFactory::getDocument();
$css = ".otherClass {}";
$css .= ".yourClass {}";
$wrap_tag = 'b';
$html_title = preg_replace("~\W\w+\s*$~", '<'.$wrap_tag.'>'.'\\0'.'</'.$wrap_tag.'>', $module->title);
$doc->addStyleDeclaration($css);
?>
<div>
<?php if ($module->showtitle != 0) : ?>
<h1><?php echo $html_title; ?></h1>
<?php endif; ?> // post your title
</div>
<div>
<?php echo $module->content; ?> // post your module content
</div>
<?php
}
Thanks to everybody for the help.
The Gantry framework can help you accomplish what you want (1st word styled one way, 2nd word styled another) - but it's a lot of overhead just accomplish that one task you're looking for. Ultimately you'll have to create a template override for your template, and then do some creative editing with php in order to get it to display that way.
There's no quick and easy way to get that done. You'll have to do some php coding on the backend and edit the template (use an override so you don't hack core files). Ultimately you'll probably have to code the php to pull apart the title, and apply formatting to each pulled apart word (or string of words as the case may be) using CSS.
Hope that helps.
