Adding infinite custom field in wordpress - php

Question

As the title explains, I am trying to add infinite custom fields for two things:
1.Name
2.Bio
Now i tried adding 1000 custom fields and upon update it showed me just 471, There's no way it exceeds and i tried this on my local environment as well as the online but same results
// Adding the metaboxes
add_action( 'add_meta_boxes', 'add_employee_meta' );
/* Saving the data */
add_action( 'save_post', 'employee_meta_save' );
/* Adding the main meta box container to the post editor screen */
function add_employee_meta() {
add_meta_box(
'employee-details',
'Employee Details',
'employee_details_init',
'post');
}
/*Printing the box content */
function employee_details_init() {
global $post;
// Use nonce for verification
wp_nonce_field( plugin_basename( __FILE__ ), 'employee_nonce' );
?>
<div id="employee_meta_item">
<?php
//Obtaining the linked employeedetails meta values
$employeeDetails = get_post_meta($post->ID,'employeeDetails',true);
$c = 0;
if ( count( $employeeDetails ) > 0 && is_array($employeeDetails)) {
foreach( $employeeDetails as $employeeDetail ) {
if ( isset( $employeeDetail['name'] ) || isset( $employeeDetail['bio'] ) ) {
printf( '<p>Name<input type="text" name="employeeDetails[%1$s][name]" value="%2$s" /> Package : <textarea name="employeeDetails[%1$s][bio]" rows="4" cols="50" >%3$s</textarea>%4$s</p>', $c, $employeeDetail['name'], $employeeDetail['bio'], 'Remove' );
$c = $c +1;
}
}
}
?>
<span id="output-package"></span>
<?php _e('Add Employee Details'); ?>
<script>
var $ =jQuery.noConflict();
$(document).ready(function() {
var count = <?php echo $c; ?>;
$(".add_package").click(function() {
count = count + 1;
$('#output-package').append('<p> Name <input type="text" name="employeeDetails['+count+'][name]" value="" /> bio : <textarea name="employeeDetails['+count+'][bio]" rows="4" cols="50" ></textarea><?php echo "Remove"; ?></p>' );
return false;
});
$(document.body).on('click','.remove-package',function() {
$(this).parent().remove();
});
});
</script>
</div><?php
}
/* Save function for the entered data */
function employee_meta_save( $post_id ) {
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
return;
// Verifying the nonce
if ( !isset( $_POST['employee_nonce'] ) )
return;
if ( !wp_verify_nonce( $_POST['employee_nonce'], plugin_basename( __FILE__ ) ) )
return;
// Updating the employeeDetails meta data
$employeeDetails = $_POST['employeeDetails'];
update_post_meta($post_id,'employeeDetails',$employeeDetails);
}
Have anyone tried adding a lot of custom fields and was there such limit as of what i am facing right now ?
Is there any way we can actually use any number of custom fields without this sort of restriction that i am having right now ?

Answer 1

You can hard code it without a plugin by adding this to you functions.
add_filter( 'postmeta_form_limit' , 'customfield_limit_increase' );
function customfield_limit_increase( $limit ) {
$limit = 1000;
return $limit;
}
I would think you could possibly end up with a performance issue going overboard with this.
Also you could run into a php limitation even with the ACF plugin mentioned above. (in PHP 5.3.9) If that is the case you can add this to your .htaccess file...
php_value max_input_vars 3000
