I am working in gravityforms to pre-populate a form with database values dynamically, which is working. I need to be able to specity which of these options is selected by default when the form is built, but I can't find the option to do so. I have seen the placeholder, but I presume this doesnt actualy select anything on the dropdown. I have been unable to find any docs or references that allow me to set the "selected" options once I have built all the text/value pairs in the array and set the choices.
The function (which I have redacted here) works fine and populates the field, I just need to populate a placeholder and/or default selected value.
add_filter('gform_pre_render_1', 'getFieldValues');
add_filter('gform_pre_validation_1', 'getFieldValues');
add_filter('gform_pre_submission_filter_1', 'getFieldValues');
function getFieldValues($form) {
global $wpdb;
foreach ($form['fields'] as $field) {
if ($field->id == '40') {
// get the list of values from the Database
$list1Q = "SELECT <data> FROM <table> WHERE <params> = <value>";
$list1R = $wpdb->get_results($list1Q);
// Generate a nice array that Gravity Forms can understand
if (!empty($list1R)) {
$list1A[] = array();
foreach ($list1A as $listItem) {
// Add current value to the array for dropdown choices
$list1C[] = array('text' => $listItem->variable, 'value' => $listItem->variable);
}
}
// Set choices to field
$field->choices = $List1C;
***** THIS IS WHERE I WOULD LIKE TO SET THE SELECTED VALUE *****
}
}
return $form;
}
If there is a better way to go about populating this field, I am open to suggestions at it seems that the form loads a bit slow using this method. Otherwise, I would love to know how to set a selected choice value after populating the choices.
the quick answer is, there is an option that i found for "isSelected" that can be included in the array when defining choices. I added a ternary operation to match on what I wanted selected and it set the "selected value for me.
$isSelected = ($listItem->variable == "value I want to select") ? true : false;
$list1C[] = array('text' => $listItem->variable, 'value' => $listItem->variable, 'isSelected' => $isSelected);
Adding the ternary choice and changing the array push allowed me to set a value as selected.

I am trying to make a form which will allow them to update their entered unique entry. Suppose there is form which is used to collect, the User Specializations
And this Specializations field is gravity forms multiselect field which is dynamically set. And as they update their specializations also updated in entries tab.
So, i just want to allow they to have this multiselect field updation.
I came across a solution to add multiselect choice dynamically but that only populate the field with all the choices not the user selected also.
So, is there is way to set the user entered choices dynamically?
Possible Solution:
Like we can get the entries and then set search criterion to current user and will get a unique entry and then after we can set these selected values in the choices.
Issue Exists with the above possible solution:
but still there is issue like it will be creating new entry as form dont know it is update operation. So can anyone help?

Is there a way to create/update form poll fields based on a content type? For example, I've got a post type called Candidate and I'd like like to dynamically update a poll list when a new Candidate is added, or when one is removed.
The reason I'm looking for this is because I'm creating a voting mechanism for this client and they have requested that users see an image, the name, and brief Bio of who they are voting for. My idea is to tie in the names so that I can target a hidden Gravity Form poll on page so when the voter clicks, it updates the corresponding named checkbox.
I can of course add each Candidate one by one, and then add each candidate one by one in the form, but was hoping there was a way to do that in code. So far I haven't found much other than filters in the Gravity Forms Documentation.
To reiterate, my question here is not the frontend connection, rather how to dynamically update/add an option in a poll field in a form when content is created for a Candidate post type.
Any help would be appreciated.
I believe the solution you're after is documented here:
http://www.gravityhelp.com/documentation/gravity-forms/extending-gravity-forms/hooks/filters/gform_pre_render/
Probably a combination of solution examples #1 and #2 on that page will fit your needs? So -
Create a category of standard Wordpress pages (category name: "Candidates"), and the pages would contain the candidate information (bio, photo, etc).
In your functions.php file for your current theme, you'd add something like the following to pull out that category's worth of posts:
// modify form output for the public page
add_filter("gform_pre_render", "populate_checkbox");
// modify form in admin
add_filter("gform_admin_pre_render", "populate_checkbox");
function populate_dropdown($form) {
// some kind of logic / code to limit what form you're editing
if ($form["id"] != 1) { return $form; }
//Reading posts for "Business" category;
$posts = get_posts("category=" . get_cat_ID("Candidates"));
foreach ($form['fields'] as &$field) {
// assuming field #1, if this is a voting form that uses checkboxes
$target_field = 1;
if ($field['id'] != $target_field) { break; }
// init the counting var for how many checkboxes we'll be outputting
// there's some kind of error with checkboxes and multiples of 10?
$input_id = 1;
foreach ($posts as $post) {
//skipping index that are multiples of 10 (multiples of 10 create problems as the input IDs)
if($input_id % 10 == 0) { $input_id++; }
// here's where you format your field inputs as you need
$choices[] = array('text' => $post->post_title, 'value' => $post->post_title);
$inputs[] = array("label" => $post->post_title, "id" => "{$field_id}.{$input_id}");
// increment the number of checkboxes for ID handling
$input_id++;
}
$field['choices'] = $choices;
$field['inputs'] = $inputs;
}
// return the updated form
return $form;
}
In a form, I have checkboxlist which has two check box (Male and Female)
User can select both of them or any of them. And values are getting save in DB.
When we populate it from DB then I want to do like if male was selected then it should select Male checkbox and disable the Female checkbox or vice versa.
The code in my View file is:
<?php if(isset($model['gender'])){
$data = $model['gender'];
if (isset($data)) {
if($data == 0)
$htmlOptions = array(
'0' => array('label'=>'MALE'),
'1' => array('disabled'=>'disabled','label'=>'FEMALE'),);
}
if($data == 1){
$htmlOptions = array(
'0' => array('disabled'=>'disabled','label'=>'MALE', ),
'1' => array('label'=>'FEMALE'),);
}
}
echo $form->checkBoxList($model, 'gender', $htmlOptions); ?>
Problem is when I am populating it is selecting the one,I selected while saving but not disabling the other one.
For this you have to use javascript because there is no way you can handle it only with PHP. Now I don't know that much JS, but the steps are easy:
Get the checkbox id's
check which one is selected
disable the other one with innerHTML in JS.
Here you have an example on how you disable checkboxes in JS
Just so you know, the JS should be placed inside the view.
I have a Zend_Form with a dropdown field.
When the user sets a value in the url this one should be selected as default value in this dropdown.
So what i do at the moment is this:
$parlang = $this->getRequest()->getParam('lang');
if($parlang){
$this->view->filterForm->getElement('ddLanguage')->setValue($parlang);
}
if ($this->getRequest()->isPost()) {
if($this->view->filterForm->isValid($_POST)){
...
...
...
No i want to check if the value of the variable is even a valid value for the dropdown? How can i check this in coorporation with the form validation. Yes i can check the variable against a array or so but this seems to be "fighting against the framework".
So what is the Zend way to do such a thing?
Edit:
My final solution for all who are interested, is:
$parlang = $this->getRequest()->getParam('lang');
if($parlang){
$ddLanguage = $this->view->filterForm->ddLanguage;
if($ddLanguage->isValid($parlang)){
$ddLanguage->setValue($parlang);
$language = $parlang;
}
}
I ran a quick test and it looks like one method you can use is Zend_Form_Element_Select::getMultiOption() to check if the language exists in the select values.
<?php
$parlang = $this->getRequest()->getParam('lang');
if ($parlang) {
$el = $this->view->filterForm->getElement('ddLanguage');
// attempt to get the option
// Returns null if no such option exists, otherwise returns a
// string with the display value for the option
if ($el->getMultiOption($parlang) !== null) {
$el->setValue($parlang);
}
}
If your Multiselect element contains a list of country, I would just populate a default in your element value according to the one in the URL.
In order to do so, you could create a custom Zend_Form_Element as follow:
class My_Form_Element_SelectCountry extends Zend_Form_Element_Select
{
protected $_translatorDisabled = true;
public function init()
{
$locale = Zend_Registry::get('Zend_Locale');
if (!$locale) {
throw new Exception('No locale set in registry');
}
$countries = Zend_Locale::getTranslationList('territory', $locale, 2);
unset($countries['ZZ']);
// fetch lang parameter and set US if there is no param
$request = Zend_Controller_Front::getInstance()->getRequest();
$lang = $request->getParam('lang', 'US');
// sort your country list
$oldLocale = setlocale(LC_COLLATE, '0');
setlocale(LC_COLLATE, 'en_US');
asort($countries, SORT_LOCALE_STRING);
setlocale(LC_COLLATE, $oldLocale);
// check weither the lang parameter is valid or not and add it to the list
if (isset($countries[$lang])) {
$paramLang = array($lang => $countries[$lang]);
$countries = array_merge($paramLang, $countries);
}
$this->setMultiOptions($countries);
}
}
You get the idea from this custom form.
If what you're trying to do isn't a Multiselect field filled by a country list but a list of language instead, then the logic is the same, you just need to change the call to the static method Zend_Locale::getTranslationList()and grab whatever information you need.
One more thing, if you just want a single element in your Multiselect element, then go for a Zend_Form_Element_Hidden.
It's a lot of "if" but I can't understand how looks like your Multiselect element exactly from your question.
Now let's take a look on the validation side, when you're using a Multiselect element, Zend_Framework automatically adds an InArray validator, which means that you don't have anything to do to check weither the data sent are correct or not. isValid is going to do it for you.
Weither a user let the default parameter and everything will be fine, or he modifies/deletes this parameter and the default parameter (en_US in this case, see code above) is going to be set as a default value for the Multiselect field.
To answer your last question, no it's not against the framework to check a variable set by a user and compare it with an array (from getTranslationList()for example). I would say it's even the recommended way to do things.
I am generating options for my dropdown using
// view.php
foreach ($plants as $row):
$options[$row->plant_id] = $row->plant_name;
endforeach;
and then lower in the HTML part of view.php
//view.php
$js = 'onChange = "plantDateDelete(\'/size/get_dates_for_plant/\'+this.value);"';
echo form_dropdown('plant_id', $options, 'Select', $js);
The dropdown show options OK, but it does NOT show 'Select' as the "selected"/default value. It shows up with the first option of the array instead.
The HTML source also shows 'Select' in form_dropdown was ignored.
I really need this dropdown to show up with 'Select' as default so as to force the user to activate the onChange function.
Any idea what is going on here or how to solve this issue?
You need to have the default option in your $options array...
So before your foreach, do:
$options = array('Select');
I should add, this will have the value of 0 in the dropdown, but as its the first element in the array it will be selected by default, unless another option is passed as the default value.
If you wanted to explicitly set this value as the default you would pass 0 as the default argument.
