Salutare!
Am reusit sa fac sa functioneze un meta_box custom in wordpress dar am nevoie pe putin ajutor, pentru ca in modul wp_debug true, imi apar 3 erori, se pare toate din aceeasi cauza. De notat ca eroarea apare doar daca nimic nu este completat in custom field-urile respective.
De exemplu, daca acest <?php echo $instructions; ?> nu afiseaza nimic pentru ca nimic nu a fost completat in acel camp, atunci apare acea eroare. Daca acel camp este completat (cu text in cazul meu), eroarea nu mai apare.
Erorile suna asa:
Liniile respective sunt corespunzatoare urmatoarelor coduri:Cod:Notice: Undefined index: custom_meta_instructions in /.../single.php on line 11
Notice: Undefined index: custom_meta_gamefile in /.../single.php on line 13
Functia corespunzatoare acestora este urmatoarea:Cod:<?php
$custom_meta = get_post_custom($post->ID);
$instructions = $custom_meta['custom_meta_instructions'][0];
$difficulty = $custom_meta['custom_meta_difficulty'][0];
$gamefile = $custom_meta['custom_meta_gamefile'][0];
?>
Chiar am nevoie de ajutor pentru ca acele erori sa nu mai apara asa ca multumesc anticipat celui care ma poate ajuta!Cod:$prefix = 'custom_meta_';
