Hi I'm trying to find the last array of $linkNumber from my for each loop as i have an image outside the foreach loop that needs the data-slide-index to be the last array plus 1. Any help how to achieve this?
<?php $linkNumber = 0;?>
<?php foreach ($variables as $variable){ ?>
<img src="$variable" data-slide-index="$linkNumber++"/>
<?php } ?>
<img src="#" data-slide-index="<?php $linkNumber + 1;?>"
If we ignore that your variables won't be printed or evaluated at all for the moment; essentially what you are doing is correct. Your problem is most of your logic isn't being executed.
You need to explicitly echo variables and evaluations should be inside a PHP block, as follows
<?php
$linkNumber = 0;
foreach ($variables as $variable) :
?>
<img src="<?= $variable; ?>" data-slide-index="<?= $linkNumber; ?>"/>
<?php
$linkNumber++;
endforeach;
?>
<img src="#" data-slide-index="<?= $linkNumber; ?>"
This should work:
<?php $linkNumber = 0;?>
<?php foreach ($variables as $variable){ ?>
<img src="$variable" data-slide-index="$linkNumber++"/>
<?php } ?>
<img src="#" data-slide-index="<?php echo count($variables) + 1;?>"
Your code seems to work except for some syntax issues. Eliminating these this code works for me:
<?php
$linkNumber = 0;
$variables = array("test", "test2");
foreach ($variables as $variable){
echo '<img src="' . $variable . '" data-slide-index="' . $linkNumber++ . '"/>' . "\n";
}
echo '<img src="#" data-slide-index="' . $linkNumber . '">';
?>
