image url field does not save

“Url” and “open in new tab” fields do not save.

version: 2.9

Reason: assets/js/acf-photo-gallery-field.js (lines 161-167):

var form = $(this).serializeArray();
...
form.push({name: "acf_field_name", value: acf.getField(form.acf_field_key).data.name});

serializeArray() creates indexed, not associative array, so form array does not have acf_field_key property, form.acf_field_key is undefined,acf_field_name field in ajax request gets incorrect value and url/target saves incorrectly.

Possible fix:

replace lines 161-167 with:

    var form = $(this).serializeArray();
    var post_id = acf.get('post_id');
    var attachment_id = form.find(x => x.name === "attachment_id")?.value;

    var acf_field_name=acf.getField(form.find(x => x.name === "acf_field_key")?.value).data.name; //change

    form.push({name: "action", value: "acf_photo_gallery_edit_save"});
    form.push({name: "post_id", value: post_id});
    form.push({name: "nonce", value: apgf_nonce});

    form.push({name: "acf_field_name", value: acf_field_name}); //change
