Counter to add seperator on foreach

2 Views

I have an foreach to add terms to a post on WordPress Which is working great. Code below: 

<h3>
<?php foreach($terms as $term) {?>
    <?php echo $term->name;?>
<?php } ?>
</h3>

However I need to add a counter so that if there is more than one term in the <h3> it adds a / between them. For instance:

<h3>Term Name</h3>
<h3>Term Name / Term Name / Term Name</h3>

This is the code I have so far however its not working. 

        <?php
        $i = 1;
        foreach($terms as $term) {

        if($i == 1){ 
         echo ' / '.$term->name;
        } else { 
            echo $term->name;
        }   
        $i++;  
        } ?>

  1. You don’t need to use a counter. Just put each $term->name in to an array, and implode it:

    echo implode(' / ', array_map(function($term) { return $term->name; }, $terms));

    Here’s a demo

  2. Please try below code.

    <?php $terms = array_values($terms); 
if( sizeof($terms) > 1){ ?>
        <h3><?php echo  implode(' / ', array_map(function($term) { return $term->name; }, $terms)); ?></h3>
<?php }else{ $term = $terms[0]; ?>
            <h3>echo $term->name;</h3>
<?php } ?>

  3. <?php
    $i = 1;
    foreach($terms as $term) {  
        if($i > 1) { 
            echo ' / '.$term->name;
        } else { 
            echo $term->name;
            $i++; 
        } 
    }
?>

  4. Here is the working solution 🙂

     <?php 
    $terms = array("Term One","Term Two","Term Three","Term Four");
    $i = 1;
    $result="";
    foreach($terms as $term)
    {
        if($i==1)
         {
            $result=$result.$term.' ';
            $i++;   
          } 
        else
            {               
                $result=$result."/".' ';
                $result=$result.$term.' ';
            }       

    }
   echo $result;    
 ?>
