I am using Gravity Forms to update user meta. The user meta has to be serialized for another plugin, so I have to catch the value and convert it using the gform_pre_submission action before it gets uploaded to the database. It is converting just fine (a:1:{i:0;s:2:"62";}), and the entries on Gravity Forms show up exactly as I want. The problem is, when I look at the usermeta values in my phpMyAdmin, they are being stored with the string length first (ie. s:19:"a:1:{i:0;s:2:"62";}";), and I'm trying to get rid of that.
The problem seems to be in the conversion somewhere, as the string length doesn't show up if I don't convert it. Here is my code:
add_action( 'gform_pre_submission_13', 'serialize_user_tags' );
function serialize_user_tags( $form ) {
$org_type_choice = rgpost( 'input_6' );
$job_type_choice = rgpost( 'input_5' );
$interest_choices = rgpost( 'input_7' );
$string_org = 'a:1:{i:0;s:2:"'.$org_type_choice.'";}';
$string_job = 'a:1:{i:0;s:2:"'.$job_type_choice.'";}';
if (!is_array($interest_choices)){
$string_int = 'a:1:{i:0;s:2:"'.$interest_choices.'";}';
} else {
$count_int = count($interest_choices);
$string_int = 'a:'.$count_int.':{';
$i_counter_int = 0;
foreach ($interest_choices as $interest_choice) {
$string_int .= 'i:'.$i_counter_int.';s:2:"'.$interest_choice.'";';
$i_counter_int++;
}
$string_int .= '}';
}
$_POST['input_6'] = $string_org;
$_POST['input_5'] = $string_job;
$_POST['input_7'] = $string_int;
}
