I want to change the default validation message for all gravity forms for the URL input only. What is the best way of doing this with gform_field_validation or is there an alternative?
Yes gform_field_validation is the way to do this.
Here's some untested code, but I think it should work. Notice the FORMID and FIELDID that you should update with the appropriate values, not saying the regex will be exactly what you want, I just found it in a quick search here: What is the best regular expression to check if a string is a valid URL?
add_filter( 'gform_field_validation_FORMID_FIELDID', 'custom_url_validation', 10, 4 );
function custom_url_validation( $result, $value, $form, $field ) {

I have a field 47 on Page 1 and a field 55 on Page 3 of a form. How do I create a gform_validation on Page 3 to prompt an error message when Field 47 < Field 55? The code below works for validation if both fields are on same page but it doesn't work for multi-page. Any idea plz?
Thanks!
// multi-page validation
add_filter( 'gform_validation', 'custom_validation' );
function custom_validation( $validation_result ) {
$form = $validation_result['form'];
// Financial Assets must be larger than Investment
if ( rgpost( 'input_47' ) < rgpost( 'input_55' ) ) {
// set the form validation to false
$validation_result['is_valid'] = false;
//finding Field with ID of 1 and marking it as failed validation
foreach( $form['fields'] as &$field ) {
//NOTE: replace 1 with the field you would like to validate
if ( $field->id == '34' ) {
$field->failed_validation = true;
$field->validation_message = 'Your Financial Assets (A) cannot be lower than your investment with us. Please fix the discrepancy.';
break;
}
}
}
//Assign modified $form object back to the validation result
$validation_result['form'] = $form;
return $validation_result;
}
I found the following information on their documentation however I'm not sure how to implement it inside the code above. Any clue? Thanks alot!
// 3 - Get the current page being validated
$current_page = rgpost( 'gform_source_page_number_' . $form['id'] ) ? rgpost( 'gform_source_page_number_' . $form['id'] ) : 1;
First, you can get the submitted page via the GFFormDisplay::get_source_page( $form_id ) method.
There are a few different ways this could be done. For simplicity, I would just bypass validation until your desired page is submitted. To do that, just add something like this:
if( GFFormDisplay::get_source_page( $form_id ) >= 3 ) {
return $validation_result;
}
...after this line:
$form = $validation_result['form'];
This would only run this validation on pages greater than page 3.
I used the script from here to do the verification.
The $result === FALSE condition was being bypassed regardless of me clicking on the re-captcha validation on my form.
So I decided to manually parse it like so:
The return looks like this if a failure:
{
"success":false,
"error-codes":[
"missing-input-response"
]
}
And if it's success it looks similar but some additional things are attached, but the main thing I targeted was the string "success":true,
With this part of the script directly below the $result variable:
$result_copy = $result;
// remove white spaces everywhere
$mod_res_copy = preg_replace('/\s+/', '', $result_copy);
$success_string = '"success":true';
if(strpos($mod_res_copy, $success_string) !== false) {
$status = "ok";
}else {
$status = "not-ok";
}
if ($status == "not-ok") {
echo "Please complete the captcha to prevent spam.";
exit;
}else {
// trigger database insert of comment or whatever
}
What I want to know is, is this wrong? Can this be spoofed? I'm using PHP as my server-side scripting language.
You are doing way more work than you need, to parse $result.
It is in JSON format, so this is all you need:
$status = json_decode($result)->success ? 'ok' : 'not-ok';
Heres the problem
I want to require a field (litters_per_year) only if another field that is a checkbox is checked. When I do this, cake is trying to force me to put a value into the field and I don't know why. I have tried setting required & allowEmpty to false & true respectively, but then my custom rule does not run.
Heres the code
NOTE: The details of the following code aren't that important - they are here to provide a scenario.
I have the following code in my VIEW which works fine:
echo $this->Form->input('litters_per_year', array(
'label' => 'Litters per year (average)'
));
I have the following code in my MODEL's public $validate:
'litters_per_year' => array(
'isNeeded' => array(
'rule' => array('isNeeded', 'litters_per_year'),
'message' => 'Please enter the litters per year average'
)
)
which is calling the custom validation method
public function isNeeded($field) {
// Check if a checkbox is checked right here
// Assume it is not... return false
return false;
}
It returns false for simplicity to solve this issue.
Let's assume that the checkbox field is named 'the_checkbox'.
At the moment your field should always fail validation, since you return false from isNeeded.
To make it work as you expect, do something like this:
(Note: replace 'ModelName' with your model name)
public function isNeeded($field) {
if ($this->data['ModelName']['the_checkbox']) {
// Checkbox is checked, so we have to require litters per year
if (empty($field)) {
// They have checked the box but have NOT entered litters_per_year
// so we have a problem. NOT VALID!
return false;
} else {
// They have checked the box, and entered a litters_per_year
// value, so all good! Everything is valid!
return true;
}
} else {
// Checkbox is not checked, so we don't care what
// the field contains - it is always valid.
return true;
}
}
Or, without the needless verbosity, this should work:
public function isNeeded($field) {
if ($this->data['ModelName']['the_checkbox']) {
return $field;
} else {
return true;
}
}
In this example, if the checkbox is checked, validation will pass if $field is truthy, and fail if it is falsey.
To be more clear, none of these lines in default language's general_lang.php work:
$lang['general_welcome_message'] = 'Welcome, %s ( %s )';
or
$lang['general_welcome_message'] = 'Welcome, %1 ( %2 )';
I expect an output like Welcome, FirstName ( user_name ).
I followed the second (not accepted) answer at https://stackoverflow.com/a/10973668/315550.
The code I write in the view is:
<div id="welcome-box">
<?php echo lang('general_welcome_message',
$this->session->userdata('user_firstname'),
$this->session->userdata('username')
);
?>
</div>
I use codeigniter 2.
You will need to use php's sprintf function (http://php.net/manual/en/function.sprintf.php)
Example from http://ellislab.com/forums/viewthread/145634/#749634:
//in english
$lang['unread_messages'] = "You have %1$s unread messages, %2$s";
//in another language
$lang['unread_messages'] = "Hi %2$s, You have %1$s unread messages";
$message = sprintf($this->lang->line(‘unread_messages’), $number, $name);
I extended Code CI_Lang class like this..
class MY_Lang extends CI_Lang {
function line($line = '', $swap = null) {
$loaded_line = parent::line($line);
// If swap if not given, just return the line from the language file (default codeigniter functionality.)
if(!$swap) return $loaded_line;
// If an array is given
if (is_array($swap)) {
// Explode on '%s'
$exploded_line = explode('%s', $loaded_line);
// Loop through each exploded line
foreach ($exploded_line as $key => $value) {
// Check if the $swap is set
if(isset($swap[$key])) {
// Append the swap variables
$exploded_line[$key] .= $swap[$key];
}
}
// Return the implode of $exploded_line with appended swap variables
return implode('', $exploded_line);
}
// A string is given, just do a simple str_replace on the loaded line
else {
return str_replace('%s', $swap, $loaded_line);
}
}
}
ie. In your language file:
$lang['foo'] = 'Thanks, %s. Your %s has been changed.'
And where-ever you want to use it (controller / view etc.)
echo $this->lang->line('foo', array('Charlie', 'password'));
Will produce
Thanks, Charlie. Your password has been changed.
This handles single 'swaps' as well as multiple
Also it won't break any existing calls to $this->lang->line.
I simply need to add a validation class that limits a numerical entry from being greater than 24.
Is this possible with CI's default validation classes or will I have to write a custom validation class?
You can use validation rule "greater_than[24]"
like for Example
$this->form_validation->set_rules('your_number_field', 'Your Number', 'numeric|required|greater_than[24]');
There's no maximum or minimum comparison function in the Form Validation Rule Reference, so you can just write your own validation function.
It's pretty straightforward. Something like this should work:
function maximumCheck($num)
{
if ($num > 24)
{
$this->form_validation->set_message(
'your_number_field',
'The %s field must be less than 24'
);
return FALSE;
}
else
{
return TRUE;
}
}
$this->form_validation->set_rules(
'your_number_field', 'Your Number', 'callback_maximumCheck'
);
Sure you can, just make your own validation function and add it as a callback to validation rule. See http://codeigniter.com/user_guide/libraries/form_validation.html#callbacks
Hence, you will have
...
$this->form_validation->set_rules('mynumber', 'This field', 'callback_numcheck');
....
function numcheck($in) {
if (intval($in) > 24) {
$this->form_validation->set_message('numcheck', 'Larger than 24');
return FALSE;
} else {
return TRUE;
}
}
