Hi just wondering if anybody can assist me in Limiting and explode ... basically it's a list of image refs seperated by comma .. the explode is working fine and showing all the image .. but i would like to limit it to 4.

 

Tried a few variations, but i kept getting a random image of a 404 page .. very strange !

Here is my code

 

<ul class="thumbs list-image clearfix">
               <?php 
                 $parts = explode(',', $row["imagerefs"]);
                 foreach($parts as $part) {
	        ?>
<li>
<a class="thumb" name="leaf" href="<?php echo $part; ?>" title="<?php echo $row["make"]; ?>">
<img src="<?php echo $part; ?>" alt="<?php echo $row["make"]; ?>" style="width:146px; height:88px;"/></a>
</li>
	        <?php
                     }
                ?>

 

Thanks folks !!

Try:

 

 

 

<?php
$parts = explode(',', $row["imagerefs"]);
$numImg = 0;
foreach($parts as $part) {
    $numImg++;

    if ($numImg <= 4) {
?>
    <li>
        <a class="thumb" name="leaf" href="<?php echo $part; ?>" title="<?php echo $row["make"]; ?>">
        <img src="<?php echo $part; ?>" alt="<?php echo $row["make"]; ?>" style="width:146px; height:88px;"/></a>
    </li>
<?php
    }
}
?>
 

Lyndsey thank you very much !!

 

That worked perfectly !

 

Superstar !

No worries

An alternative method, for anyone interested - not that Lyndey's answer is incorrect by any means

<?php
$parts = explode(',', $row["imagerefs"]);
$numImg = 0;
foreach($parts as $part) :
    if (++$numImg > 4) break;
?>
    <li>
        <a class="thumb" name="leaf" href="<?php echo $part; ?>" title="<?php echo $row["make"]; ?>">
        <img src="<?php echo $part; ?>" alt="<?php echo $row["make"]; ?>" style="width:146px; height:88px;"/></a>
    </li>
<?php endforeach ?>

Slightly more efficient in that it prevents unnecessary loops if $parts happens to contain a large number of items. Also uses more shorthand for code tidy-up!

Thanks for this Andy, very useful

This is maybe gonna sound a bit strange, but is it possible to exclude the first $ part found so instead of showing the first 4 images, show image 2,3,4,5 ?

 

I know it's a strange request, but i have my reasons lol

<?php

$parts = explode(',', $row["imagerefs"]);

unset($parts[0]); // Add this line

$numImg = 0;

foreach($parts as $part) :

    if (++$numImg > 4) break;

?>

    <li>

        <a class="thumb" name="leaf" href="<?php echo $part; ?>" title="<?php echo $row["make"]; ?>">

        <img src="<?php echo $part; ?>" alt="<?php echo $row["make"]; ?>" style="width:146px; height:88px;"/></a>

    </li>

<?php endforeach ?>

 

Oh wow, awesome .. Thanks for that Andy ! Great work !

No problem buddy
