Question

Data comes from WordPress metabox in a form of single long array.

The data that I insert in metabox looks like this:

Rhine Riesling1|0,75 l|9,50 &euro

Rhine Riesling2|0,75 l|9,50 &euro

Rhine Riesling3|0,75 l|9,50 &euro

Rhine Riesling4|0,75 l|9,50 &euro

Final output should look like this:

<ul class="listmenuitems" id="listingmenu_1">
    <li><p>Rhine Riesling1 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling2 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling3 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
    <li><p>Rhine Riesling4 <span>0,75 l</span></p> <span class="listmenuprice">9,50 &euro;</span></li>
</ul>

How would I cut the array values into pieces considering the separator | and then loop through it to create a correctly formatted <li><p>?

I’m reading about PHP’s explode() at the moment.

Answer 1

You can use the PHP explode command. http://php.net/manual/en/function.explode.php

Loop through your array, on each entry call: explode(“|”, $entry);
then you can print out what you want like so:

$input_arr[];
echo '<ul class="listmenuitems" id="listingmenu_1">';
for($i=0;i<sizeof($input_arr);$i++) {

    $e = explode("|",$input_arr[$i]);
    echo "<li><p>" . $e[0] . "<span>" . $e[1] . "</span></p> <span class=\"listmenuprice\">" . $e[2] . "</span></li>";

}

Note there is on error checking and it is assumed that you have a complete and well formed array input.

Updated to add foreach 😉
And if the foreach loop is your fancy…

$input_arr[];
echo '<ul class="listmenuitems" id="listingmenu_1">';
foreach($input_arr as $i) {

    $e = explode("|",$i);
    echo "<li><p>" . $e[0] . "<span>" . $e[1] . "</span></p> <span class=\"listmenuprice\">" . $e[2] . "</span></li>";

}
