Question

I am trying to get two foreach loop by explode with two delimiters <> and "\n" but getting error. Warning: Invalid argument supplied for foreach()

Here is my code

<?php

    $specifications = $scooter_meta->get_the_value('specifications');

    $titles = explode('<>', $specifications);

    $descs = explode("\n", $specifications);

    echo '<dl>';

    foreach($titles as $title => $descs){

        echo '<dt>' . $title . '</dt>';

        foreach($descs as $desc){
            echo '<dd>' . $desc . '</dd>';
        }

    }

    echo '</dl>';

?>

The value entering into textarea something like this Title here<>this is the first scooter ever made.
Title here 2<>another line for specification In fact I would like to make it like <title 1> here detail text

Thanks a lot

Answer 1

actually you should do something like this

<?php

$specifications = $scooter_meta->get_the_value('specifications');

$descs = explode("\n", $specifications);

echo '<dl>';

foreach($descs as $desc){

    $title = explode('<>', $desc);

    echo '<dt>' . $title[0] . '</dt>';
    for($i=1; $i<=count($title); $i++){
        echo '<dd>' . $title[$i] . '</dd>';
    }

}

echo '</dl>';

?>
