I need some help with saving my meta data from a post. On the editpage I have the following input fields

<input type="text" name="data[color][]" value="red"/>
<input type="text" name="data[color][]" value="blue"/>
<input type="text" name="data[size][]" value="small"/>
<input type="text" name="data[width][]" value="30"/>
<input type="text" name="data[width][]" value="32"/>

If I click on save / update post the array is saved as

array(
    color => array("blue"),
    size => array("small"),
    width => array("32"),
);

It has to be saved as

array(
    color => array("red", "blue"),
    size => array("small"),
    width => array("30", "32"),
);

Wordpress get only the last items.

How can I fixed this?

  • Hi WebElaine this does not fix my issue :( I think the issue is in the serialize function from Wordpress. Is it possible to disable the serialize for these inputs?

  • No, postmeta arrays are always serialized. It might be worth looking into a simpler postmeta structure - i.e. save the color as one piece of postmeta, the size as another, the width as another.
