Avoiding save_post to run your code twice

June 2, 2015 The Compilator WordPress

When attaching a function in functions.php to save_post I found out it runs my code twice. Finally found a solution using:

$post_type = get_post_type( $post_id );
		if ($post_type=='revision')
		{
			return;
		}
		if ((defined('DOING_AUTOSAVE') && DOING_AUTOSAVE )||$_POST['post_type']=='revision')
		{
			return;
		}

$post_type = get_post_type( $post_id );

if ($post_type=='revision')

{

return;

}

if ((defined('DOING_AUTOSAVE') && DOING_AUTOSAVE )||$_POST['post_type']=='revision')

{

return;

}

Getting multiple checkbox values in PHP

November 4, 2014 The Compilator PHP

If you give the checkboxes the same name, ending in [], the values are returned as an array.

<input type="checkbox" name="fruit[]" value="grapefruit" />

1 2	<input type="checkbox" name="fruit[]" value="apple" /> <input type="checkbox" name="fruit[]" value="grapefruit" />

Then in PHP …

if( isset($_POST['fruit']) && is_array($_POST['fruit']) ) {
foreach($_POST['fruit'] as $fruit) {
echo "I have a {$fruit}!";
}
$fruitList = implode(', ', $_POST['fruit']);
}

if( isset($_POST['fruit']) && is_array($_POST['fruit']) ) {

foreach($_POST['fruit'] as $fruit) {

echo "I have a {$fruit}!";

}

$fruitList = implode(', ', $_POST['fruit']);

}
