I have a procedural while loop that echos out rows in my DB like:
echo '<tr align="left"> <td>'.$row['address'].','.$row['state'].'</td>'.
'<td><a href="'.$row['shopurl'].'">'.$row['datedesc'].'</td>'.
'</tr>';
And works great! The problem now is that I need to add a "SOLD OUT" png across the address & state, of only one (currently) of the rows. I have CSS:
#sold-out{
background-image: url("/graphics/png/soldout.png");
}
With the image as the back-ground.
How can I add a Z-Index to php inside a While loop?
Thanks in advance!
You do not add z-index to PHP, you add it to CSS. However, in this case, you can simply print out an absolutely positioned div with the image in the td that you want.
PHP
foreach ($rows as $row) {
echo '<tr align="left">
<td>';
//conditional to determine if row is sold out
if ($row['soldOut'] === 'yes') {
echo '<div class="sold-out"> </div>';
}
echo $row['address'].','.$row['state'].'</td>'.
'<td><a href="'.$row['shopurl'].'">'.$row['datedesc'].'</td>'.
'</tr>';
}
CSS
.sold-out {
position:absolute;
background-image: url("/graphics/png/soldout.png");
opacity: 0.8;
top: 0;
left: 0;
right: 0;
bottom: 0;

Having a bit of an issue here. Could use some insight. I'm displaying user created events to visitors to my website. I'm using a while loop to display everything that hasn't not yet already passed. My goal is to display two separate events right next to each other, then another two below that and so on. Currently I'm using the flex box css property to achieve this, but it's only displaying the output vertically and not the way I want it to, meaning it's only putting one event per line. Here is my current output for displaying the events.
include 'db_connect.php';
$event_type = $_POST['event_type'];
$state = $_POST['state'];
$current_date = date("Y-m-d");
$sql = "SELECT * FROM events WHERE event_type LIKE '%".$event_type."%' AND state LIKE '%".$state."%' AND end_date > '$current_date' ORDER By end_date ASC";
$result = mysqli_query($conn, $sql);
if (isset($_POST['search-events']) && !empty($event_type) && !empty($state)) {
while($row = mysqli_fetch_array($result)) {
$event_name= $row['event_name'];
$image = $row['image'];
$start_date = $row['start_date'];
$end_date = $row['end_date'];
$start_time = $row['start_time'];
$end_time = $row['end_time'];
$street = $row['street'];
$city = $row['city'];
$state = $row['state'];
$zip_code = $row['zip_code'];
$id = $row['event_id'];
echo '<div class="filter-wrap">';
echo '<div id="filter-boxes">';
echo '<div id="list_image"><img src="'.$image.'"></div>';
echo '<div id="list_name">'.$event_name.'</div>';
echo '<div id="list_date">'.$start_date. ' - ' .$end_date. '</div>';
echo '<div id="list_time">' .$start_time. ' - ' .$end_time. '</div>';
echo '<div id="list_location">'.$street.''.$city.''.$state.''.$zip_code.'</div>';
echo '</div>';
echo '</div>';
}
}
Then there's the css that I'm using.
.filter-wrap {
display: flex;
flex-direction: row;
padding: 10px;
justify-content: center;
align-items: center;
}
#filter-boxes {
border: 2px solid #999;
text-align: center;
width: 50%;
height: 150px;
}
As you can see, I'm using the flex property inside the container that holds each of the individual boxes that holds each event. I have the flex direction set to row since I want it to display horizontally, then go the next line after it runs out of room on each line.
I tried a few things. I tried switching to the css column count property but didn't get the results I was expecting. I honestly probably didn't tweak with that property enough, but I have my heart set on the flex box property. I also tried setting the flex direction to column and also tried adding an inline-block display property to the boxes that are suppose to repeat on the while loop with each event. I'm finding this online that are kind of similar to my issue, but not quite. One uses javascript, but this can obviously also be accomplished somehow with php. I also found several articles talking about centering the content using flexbox, which is not the goal here.
Try move your .filter-wrap div element to outside of the while() {} loop.
Your current coding:
while() {
echo '<div class="filter-wrap">';
echo '<div id="filter-boxes">';
// content goes here...
echo '</div>';
echo '</div>';
}
will result in following structure where each .filter-wrap only container a single child .filter-boxes, which will always results in vertical presentation:
<div class="filter-wrap">
<div id="filter-boxes"> content </div>
</div>
<div class="filter-wrap">
<div id="filter-boxes"> content </div>
</div>
<div class="filter-wrap">
<div id="filter-boxes"> content </div>
</div>
For horizontal presentation, the correct structure should be one .filter-wrap consists of multiple .filter-boxes childs:
<div class="filter-wrap">
<div id="filter-boxes"> content </div>
<div id="filter-boxes"> content </div>
<div id="filter-boxes"> content </div>
</div>
So you can try change your coding to:
echo '<div class="filter-wrap">';
while() {
echo '<div id="filter-boxes">';
// content goes here...
echo '</div>';
}
echo '</div>';
Snippet for demo to you the coding logic result. It is in JS but you just have to apply the same in your PHP
Hope it helps and Happy coding!

I'm trying to show total price in a table.
I have 2 arrays where one is the names of the cars and second is the prices of each one.
I've managed do display the prices and the names inside the table,
but the thing is that i have a "checkbox" thing that shows if car is sold or not...
I'm trying to make the total calculation that calculate the total price of all checked checkboxes.
That means - when checkbox is on, the variable of total price should add that car's price to it.
here is how it should looks like:
I must mention that I've just started to learn php at collage,
here's the array and the variable:
<?php
$cars = array ("ford","fiat","renault","mazda");
$prices = array(100,80,90,120);
$sold = '<input type="checkbox" name="sold">';
?>
I added up basic style for my table (in the same php file)
<style>
table {
font-family: arial, sans-serif;
border-collapse: collapse;
width: 100%;
}
td, th {
border: 1px solid #dddddd;
text-align: center;
padding: 8px;``
}
</style>
and the php code for the table:
<?php
$cars = array ("ford","fiat","renault","mazda");
$prices = array(100,80,90,120);
$sold = '<input type="checkbox" name="sold">';
?>
<h1>list of cars</h1>
<table>
<th>name</th>
<th>price</th>
<th>sold</th>
<?php
for($i=0;$i<count($cars);$i++){
echo
"<tr>
<td>$cars[$i]</td>.
<td>$prices[$i]$</td>.
<td>$sold</td>.
</tr>";
}
?>
</table>
How can I calculate the amount of all checked checkboxes prices?
imvain2’s answer would be your best choice as it does not require a client-server roundtrip.
However, if you would like to do this in php, you need to associate the checkbox with the car in some way.
One way would be to tweak your for loop like so
for($i = 0; $i < count($cars); $i++) {
echo (
"<tr>
<td>{$cars[$i]}</td>
<td>{$prices[$i]}$</td>
<td><input type=\"checkbox\" name=\"sold[]\" value=\"{$prices[$i]}\"></td>
</tr>"
);
}
So when the form containing the table is submitted to the server you can do the calculation like
$total = 0;
foreach ($_POST['sold'] as $value) {
$total += (int)$value;
}
I would modify the checkbox to include the price as a data-attribute and put it within the for loop not outside of it.
$sold = '<input type="checkbox" data-price="$prices[$i]" name="sold">';
then in javascript just loop through the checkboxes and an event listener that checks for checked.
function showTotal(els) {
total = 0;
els.forEach(function(el) {
if (el.checked) {
total += +el.getAttribute("data-price");
}
});
document.querySelector("#total").innerHTML = "$" + total.toFixed(2)
}
sold = document.querySelectorAll("[name='sold']");
sold.forEach(function(el) {
el.addEventListener("change", function(ev) {
showTotal(sold)
});
});
to show the total you will need a div to hold the total
<div id="total"></div>
**Note: please fix my english if needed.
please notice that the hole code is written in single php file.
after quit a bit of time, i was mange to fix my code.
first, as suggest here before, the JS code that was given was written in jquery, i haven't learned that part of js yet, therefor i wrote the code with the help of my friend in js using dom.
CSS:
<style>
body {
text-align:center;}
table {
font-family: arial, sans-serif;
border-collapse: collapse;
width: 50%;
margin-left: auto;
margin-right: auto;
margin-top:15%;
}
th{
}
td, th {
border: 1px solid #dddddd;
text-align: center;
padding: 8px;
}
tr:nth-child(even) {background: #CCC}
tr:nth-child(odd) {background: #FFF}
</style>
JS: (the location of the script tag doesn't matter at this point, but iv'e located it at the top of the php file inside header content.
<script>
function calcTotal() {
let sum = 0;
for (let index = 0; index < 4; index++) {
let priceAsStr = document.getElementById("price" + index).innerHTML;
let price = parseInt(priceAsStr);
let soldOrNot = document.getElementById("soldOrNot" + index).checked;
if (soldOrNot == true)
{
sum = sum + price;
}
}
document.getElementById("sum").innerHTML ="$" + sum;
}
and finally, for the body:
<?php
$cars = array("Ford","Fiat","Renault","Mazda");
$prices = array(100,80,137,453);
?>
<table>
<tr>
<th>Cars</th>
<th>Price</th>
<th>Sold</th>
</tr>
<?php
$sum = 0;
for ($i=0; $i < 4; $i++) {
echo "<tr id='row$i'>
<td>{$cars[$i]}</td>
<td id='price{$i}'> {$prices[$i]}$</td>
<td><input type='checkbox' id='soldOrNot{$i}' name='sold{$i}' onClick='calcTotal()' value=''> </td>
</tr>";
}
?>
</table>
<h1>Total Price: <span id="sum">0</span></h1>
I have two arrays which I use implode() on to convert into strings which are then echoed out.
Ideally i'd like the 1 value from the one string to be next to the other value in the other string, prefably nested inside a
<p></p>
Here's the code I'm using to issue a line break after every value, wrap it in a div, and float it.
<?php
echo '<div class="wrapper"><div style="text-align:left; float:left;"
class="glue">';
echo implode('<br>',$test);
echo '</div>';
echo '<div style="text-align:right; float:right;" class="glue">';
echo implode('<br>',$_POST);
echo '</div></div>';
?>
This works well for now as both divs sit next to each other within my container but it would be easier if the values were inside P tags instead so I could easily put an image in-between them.
I've added some images below to better demonstrate what I'm going for.
The first one is what I've tried and the second one is what I would like.
Is it what you want?
<style type="text/css">
p{
overflow: hidden;
}
span.left{
float: left;
}
span.right{
float: right;
}
</style>
<?php
foreach($test as $k=>$v){
echo '<p><span class="left">'.$test[$k].'</span><span class="right">'.$_POST[$k].'</span></p>';
}
That is not possible until you split the paragraph tag into 2 halves.
Try this,
.div1 {
float: left;
}
.div2 {
float:right;
}
.div2 {
float:right;
text-align: right;
}
<p>
<div class="div1">Left Text</div>
<div class="div2">Right Text</div>
</p>
if both arrays have the same length the most simple example woud look like this:
<?php
$test[0] = "a";
$test[1] = "b";
$test[2] = "c";
$test[3] = "d";
$test2[0] = 1;
$test2[1] = 2;
$test2[2] = 3;
$test2[3] = 4;
for($i=0;$i<count($test);$i++)
{
echo "<p><nobr>".$test[$i] . "</nobr> <nobr style='float:right;'>" . $test2[$i] . "</nobr></p>";
}
if you wanna test to see if it fits just paste the code here
I want to make all the rows in the same size, but rows height with data is large. I want to fix this row size for empty rows. Table class name is demo.
Demo
<?php
while($fet=mysql_fetch_assoc($sql1))
{
$id=$fet['c_id'];
$address=$fet['address'];
$chk=$fet["c_name"];
$in=$in+1;
echo "<tr>";
echo "<td style='align:center'><a class='astext' href='client_view.php?cid=".$fet["c_id"]."'>".$fet["c_name"]."</a></td>";
echo "<td style='align:center'><a class='ima' href='client_details.php?cid=".$fet["c_id"]."'><img src='image/edit1.png' alt='edit' style='width:20px; height:20px' title=Edit></a></td><td style='align:center'>
<a class='ima' href='clients.php?del=".$fet["c_id"]."'><img src='image/delete1.png' alt='delete' style='width:20px;height:20px' title=Delete></a></td>";
echo "</tr>";
}
if ($in < 10) {
$empty_rows = 10 - mysql_num_rows($sql1);
for ($m = 0; $m < $empty_rows; $m++) {
echo '<tr><td></td><td></td><td></td></tr>';
}
}
?>
You need to add following CSS in your code.
.demo td{
height:20px;
}
Demo
Add fixed height to tr like
table tr {
height: 40px;
box-sizing: border-box;
}
check fiddle: http://jsfiddle.net/4gqgzdL8/1/
If you need box-sizing you can use it otherwise don't use
Try to set height and line-height for td like this: Demo
.demo td {
line-height:28px;
height:28px;
}
I have the following css code:
#Layer3
{
position:absolute;
width: 89%;
height: 40%;
left: 10%;
top: 56%;
background-color: #f1ffff;
}
#Layer3 h1
{
font-size: medium;
color: #000033;
text-decoration: none;
text-align: center;
}
.tableheader {
border-width:10px; border-style:solid;
}
.tablecontent {
height: 95%;
overflow:auto;
}
However, when I use this PHP to generate the html
echo '<div id="tableheader" class="tableheader">';
echo "<h1>{$query} Auctions</h1>" . "\n";
echo "</div>";
echo '<div id="tablecontent" class="tablecontent">';
echo "<table border='0' width='100%'><tr>" . "\n";
echo "<td width='15%'>Seller ID</td>" . "\n";
echo "<td width='10%'>Start Date</td>" . "\n";
echo "<td width='75%'>Description</td>" . "\n";
echo "</tr>\n";
// printing table rows
foreach ($rows as $row)
{
$pk = $row['ARTICLE_NO'];
echo '<tr>' . "\n";
table contens generated in here
echo '</tr>' . "\n";
}
echo "</table>";
}
echo "</div>";
which generates this html:
<div id="tableheader" class="tableheader">
<h1>hardy Auctions</h1>
</div>
<div id="tablecontent" class="tablecontent">
<table border='0' width='100%'>
<tr>
<td width='15%'>Seller ID</td>
<td width='10%'>Start Date</td>
<td width='75%'>Description</td>
the rest of table stuff
</div>
The stylesheet is correctly referenced so I am unsure what is causing the error. But there is no border around tableheader at all. Both of these layers are in Layer3 which no longer displays properly on the page.
#tableheader {
border: 10px solid #000;
}
Try giving it a color.
EDIT: since its id is tableheader, try changing the style selector to be an id. You could also try using !important to see if anything is overriding your class selector.
Specificity values:
inline: 1000; id: 100, class: 10, element: 1
!important trumps all other non-important declarations.
Start by browsing the HTML DOM in the rendered page either using Firebug in Firefox or using the IE Developer Toolbar in IE.
That way, you can see what styles are actually associated with the element in the rendered page. It's a lot easier to debug the issue from there.
One possibility is that there's a syntax error somewhere in the CSS file causing the styles not to be applied correctly.
I've just had a quick look at this and it seams fine, I've also created a local copy of these and the styles work out okay as well, I get a nice thick black border around the h1 text.
So from what your explaining something is either overwriting the styles, or the styles aren't being applied to the page.
