Ayuda con datos Lista desplegable. Tengo dos archivos php, uno es el "form.php" donde tengo un formulario de envió con un campo desplegable (location) con 4 opciones a elegir.
Este funciona bien.
El otro archivo es el edit.php donde el usuario puede editar su anuncio, en este aparecen todos los campos del formulario anterior incluido el campo desplegable (location) con los datos que añadió.
El problema es que si realiza o no cambios y le da al botón de guardar, el formulario de edit.php detecta el campo (location) como vació, teniendo en cuenta que este campo le muestra una de las 4 opciones que eligio.
el campo location de edit.php es este.
Código PHP:
<p><label><b>Location </b> *(Options)<br />
<select name='location' id='location' class='postform' >
<option value="<?php if ($hfield == '3') { echo $errcolor; } ?>" ><?php echo get_post_meta($getmyad->ID, "location", true); ?> </option>
<option value="Option 1">Option 1</option>
<option value="Option 2">Option 2</option>
<option value="Option 3">Option 3</option>
<option value="Option 4">Option 4</option>
</select></label></p> y el codigo entero de edit.php es este.
