Right, I'm banging my head against a wall here. I'm sure it's something incredibly simple but I keep getting undefined index errors on all of these variables.
function meta_genus_species() {
global $post;
if (isset($post)) {
$custom = get_post_custom($post->ID);
}
if (isset($custom)) {
$genus = $custom["genus"][0];
$species = $custom["species"][0];
$etymology = $custom["etymology"][0];
$family = $custom["family"][0];
$common_names = $custom["common_names"][0];
}
?>
<label>Genus:</label>
<input name="genus" value="<?php if(isset($genus)) { echo $genus; } ?>" />
<label>Species:</label>
<input name="species" value="<?php if(isset($species)) { echo $species; } ?>" />
<p><label>Etymology:</label><br />
<textarea cols="50" rows="5" name="etymology"><?php if(isset($etymology)) { echo $etymology; } ?></textarea></p>
<label>Family:</label>
<input name="family" value="<?php if(isset($family)) { echo $family; } ?>" />
<label>Common Names:</label>
<input name="common_names" value="<?php if(isset($common_names)) { echo $common_names; } ?>" />
<?php
}
I get this for every variable:
Notice: Undefined index: genus in [...]sf-species-profiles.php on line 207
Any ideas?
