I'm trying to check if the current URL equals the desired URL for making the link class active (Bootstrap).
Example
<?php
If ($currenturl = "show.php?name=123") {
?><li class="active"><a href="show.php?name="123"">123</a></li><?php
}else{
?><li class=""><a href="show.php?name="123"">123</a></li><?php
}
?>
Current URL -> $currenturl = $_SERVER['REQUEST_URI']
Now, I have this if I'm on show.php?name=456
Make sure you have the correct comparison inside the if. You're currently using the assignment operator:
Note the difference:
if($currenturl = "show.php?name=123") // assignment =
// changes $currenturl to "show.php?name=123"
// and then tests if("show.php?name=123") equivalent to if(true)
// see also http://stackoverflow.com/questions/5940626/evaluation-of-assignment-in-php
if($currenturl == "show.php?name=123") // comparison ==
Second: You have set $urlpage but comparing $currenturl. Use $urlpage
Code:
<?php $urlpage = $_SERVER['REQUEST_URI']; ?>
<?php if ($urlpage == "/show.php?nom=123") { ?>
<li class="active"><a href="/show.php?nom=123">123</a></li>
<?php } else { ?>
<li class=""><a href="/show.php?nom=123">123</a></li>
<?php } ?>
An alternative using a ternary operator:
<li <?php echo ($urlpage == "/show.php?nom=123") ? 'class="active"' : ''; ?>><a href="/show.php?nom=123">123</a></li>
Applying to all pages:
<?php $pages = array('123', '456', '789'); ?>
<ul>
<li <?php echo (!isset($_GET['nom']) ? 'class="active"' : ''); ?>><a href="show.php">Home</a></li>
<?php foreach($pages as $page): ?>
<?php if (isset($_GET['nom']) && $_GET['nom'] == $page) { ?>
<li class="active"><a href="/show.php?nom=<?php echo $page; ?>"><?php echo $page; ?></a></li>
<?php } else { ?>
<li class=""><a href="/show.php?nom=<?php echo $page; ?>"><?php echo $page; ?></a></li>
<?php } ?>
<?php endforeach; ?>
</ul>
show.php?name= but with no 123 or other.
An alternate way is to use the $_GET
if(isset($_GET['name']))
if($_GET['name'] == '123')
...
and so forth
If ($_GET['name'] == '123') but I get an error : Notice: Undefined index: name in C:\xampp\htdocs\cadeau noel\cadeau.php on line 40. Line 40 -> If ($_GET['name'] == '123') {
if(isset($_GET['name'])) if your URL does not have the ?name=123 or name=124, name=125 etc at the end of the URL, it will just give a warning. So either earlier in the code add if(!isset($_GET['name'])) $_GET['name'] = '';
