I would like to add Delete button next to my file Upload option in my plugin settings.
At this moment I am using Settings API, using form below.
<form method="post" action="options.php" enctype="multipart/form-data">
<?php
settings_fields("mw_options");
do_settings_sections("mw_options");
submit_button();
?>
</form>
It works great, I have about 10 fields in the form, one of them is file upload that adds attachments to a Woocommerce e-mails. Everything works great, but I would like to add Delete button next to the Upload button in my form, so I can use updated_option or delete_option hook, or something more suited.
I can not figure out, how to do that.
Now I use my own delete_attachment.php and formaction on the button to get the job done, but I would like to do more of this later and I feel there is a better way.
function mw_options_wc_order_attachement_1()
{
?>
<input type="file" name="mw_options_wc_order_attachement_1" id="mw_options_wc_order_attachement_1" value="<?php echo get_option('mw_options_wc_order_attachement_1'); ?>" />
<?php echo get_option("mw_options_wc_order_attachement_1"); ?>
<input type="submit" name="mw_options_wc_order_attachement_1" formaction="<?php echo plugins_url( 'delete_attachment.php' , __FILE__ );?>" formmethod="post" value="Delete">
<?php
}
How can I create another button within the main option's area that would execute some delete script I have?

Reset to default 1I managed to add delete button this way, it also may be used to add any extra submit button.
Create a submit button with name and array attribute:
function mw_options_wc_order_attachement_1()
{
?>
<input type="file" name="mw_options_wc_order_attachement_1" id="mw_options_wc_order_attachement_1" value="<?php echo get_option('mw_options_wc_order_attachement_1'); ?>" />
<?php echo get_option("mw_options_wc_order_attachement_1"); ?>
<input type="submit" name="submit[delete_attachment_1]" class="button button-primary" value="Delete" />
<?php
}
Register setting with callback function, mw_options_wc_order_attachement_1_handle is the name of the function in my case.
register_setting("mw_options", "mw_options_wc_order_attachement_1", "mw_options_wc_order_attachement_1_handle");
Make the callback function something like this:
function mw_options_wc_order_attachement_1_handle($options)
{
if (isset($_POST["submit"]))
{
$submit_button = $_POST["submit"];
if (isset($submit_button["delete_attachment_1"]))
{
// delete file
wp_delete_file('YOUR-FILE-SERVER-PATH');
return ''; // returns empty option value to settings
}
}
}
