Pref-fill fields on Gravity Forms - php
I would like to pre-fill a registration form for 2021 school year using last year's info and send out invitations to all parents.
The form all "Allow prefill" turned on for all needed fields. The prefill field name the the 'pf'&the admin name.
I tried sending myself an email with a URL containing the prefill fields=last year's data.
The obvious problem is security since the link contains personal information. So that won't work.
Next I wrote a php function (I initially put the data into an array during development) that will read a csv file on my server that contains the personal information.
I installed it into Gravity forms as a plug-in. Unfortunately, I am not familiar enough with php functions so I was unable to filter out extraneous calls to the function. It needs to run only for a specific form ID. In addition, I could not understand the part in the Gravity forms documentation regarding the sub function, so it ran every time I clicked on the web site and bombed the site.
My plan was to send an email with an account number and password, and once logged in, the function will run and prefill the fields for that one customer.
I would appreciate help either with this function, or a better way to prefill the fields.
Thanks for your help.
Here's the code:

I would suggest using the gravity_form function which allows you to pass an array of dynamic population parameter keys with their corresponding values to be populated.
Furthermore, if you did not want to require a login prior to accessing the form you could assign a unique ID to each user which would be defined as a URL parameter to identify and retrieve the required field data.
For example:
www.school.com/signup/?user=unique_complex_user_identier
Hits a template with a gravity form
URL parameter read and decoded to identify corresponding user, else fail.
User data passed into form

How to use PHP global variable for 2 functions?
I'm trying to create an interface where a workshop description can be updated on the server after it has been created by a user. There is a text field and a button that brings up the workshop by the number it was assigned. (This is also the name of the directory in the submissions/workshop# on the server). When I set the variable $workshopPath using this method, I want to be able to access this global variable when a text input is filled out with the string to update the title of the workshop. The $workshopPath is registering as an empty string in the 'updateTextItems' function, so it is writing the text file to the root directory instead of to the correct workshop directory. I thought I was correctly referencing the global variable within the functions, but this isn't working. I also tried using $GLOBALS['workshopPath'], but that isn't working either. Can someone help me figure out how to pass the variable to the second function? Thanks :-)
<?php
$workshopPath;
if (isset($_POST['gotoWorkshop'])) {
if (empty($_POST['numberInput'])) {
echo "Please enter a valid workshop number";
} else { //Assign the name variable form the posted field info if one was entered.
$workshopNumber = stripslashes($_POST['numberInput']);
global $workshopPath;
$workshopPath = "submissions/" . $workshopNumber . "/";
}
}
if (isset($_POST['updateTextItems'])) {
if ($_POST['titleInput']) {
//Assign the name variable form the posted field info if one was entered.
$titleInput = stripslashes($_POST['titleInput']);
}
if ($titleInput) {
global $workshopPath;
$titleFile = fopen($workshopPath . "title.txt", "w") or die("There was an error creating the title file.");
fwrite($titleFile, $titleInput);
fclose($titleFile);
}
}
?>
Do I understood you correct? The user fill in the a form for the workshop click submit and get an othewr form for the text? My guess is you sen to requests to the server. So $GLOBAL will not work for you. It only works per request and I think most time you do not realy need it. If you want to save some values across requests, you need a session when you start your session. After you have started your session with session_start() you can use $_SESSION[] to store and get your value
WordPress Wedding RSVP using Gravity Forms
I am building my wedding website and want to integrate an RSVP form using Gravity Forms. The issue I am running into is how to set certain guest that have +1's. I would like to show an additional guest entry (First Name, Last Name, Meal Option) when the initial First Name and Last Name has been populated. How would I go about doing this? Any help would be great! Thanks in advance!
Here is how I'd solve this problem:
First, you need to put everything in the DB, the easiest way would be to either do it manually or somehow loop through an array/CSV calling add_option($key, $value) Again, I would recommend a mobile/phone number as they'll be unique so you don't pull the wrong "John Smith". I'll assume you'll keep it basic with $key as the unique identifier and $value as boolean as to whether to show additional info. Interestingly, by default, if not found get_option($key) will return false and therefore not show your additional data, which I would assume you'd want anyway. If you'd rather it return true just pass true as the second argument.
Now for your answer:
Your URL is something like https://somesite.com/rsvp?id=1234.
function allowed_plus_one() {
$id = $_GET["id"];
$allowed = get_option($id);
return $allowed;
}
Then assumedly it'll be something like
if (allowed_plus_one()) {
// show form with plus one
} else {
// show form without
}
EDIT:
Keeping separate incase this has already been viewed.
You should also be checking for the existence of $_GET["id"] and behaving accordingly. eg:
if (isset($_GET["id"] && !empty($_GET["id"]) {
//do logic above
} else {
//here by mistake so don't show any form?
}
PHP Codeigniter: Passing dynamic form data to a view without having to refetch from the database upon validation errors
I am making a basic signup page using PHP Codeigniter. On the signup page, I ask the user to select from a selection of categories (via a <select> html element). These categories are stored in a list in my MySQL Database. My current method is to fetch this list from the DB when the user calls the function to load the page and then display it to them. However, if the user enter's incorrect data and the page must be reloaded with the validation errors, the variable that holds the data in the list seems to be cleared, and I must refetch the list data from the database before redisplaying the page. I believe there's something in the documentation about how to set this variable to be permanently available but upon looking again, I had no luck in finding it. Could anyone possibly point me in the right direction? It seems silly to me to have to need to refetch this data every time (I know that people won't be putting in wrong info often, but this will come in handy in a few situations). NOTE: This is not an issue regarding remembering user selections.
this example is for a select drop down list using ci form helper
(i'm modifying this from another form so hopefully its all correct)
the Array of select values is: $categoryarray
the drop down field name is 'category'
the default value is $defaultcategory
a css class to style (bootstrap etc): $dropclass = 'class="input-medium"';
the line of code is:
form_dropdown('category',$categoryarray,set_value('category',$defaultcategory),$dropclass).form_error('category');
the form_error('category'); at the end is for showing a validation error message
and even though there is a default value - if the form fails validation from another field in the form - this will 'remember' what the user selected.
EDIT !
ok there is good and bad news.
bad news - if the categories are coming from a database then you need to get them again.
good news - CI remembers what category the user selected from the drop down list.
and the bad news actually isn't that big a deal - if you create the category array in your model. then its just one line of code to add to the validation.
// In the Model
function makedropdown() {
// get your category list
$cats = $this->getAllCategories() ;
$categoryarray = array();
// make the array
foreach ( $cats->result() as $row ) {
$categoryarray[$row->category] = $row->category ; }
return $categoryarray ;
}
someone has filled out the form, we run validation, validation fails. in the controller:
if ( $this->form_validation->run($formrules) == FALSE ) {
// get the categoryarray
$data['categoryarray'] = $this->categorymodel->makedropdown() ;
// load form again
$this->load->view( 'myform', $data ); }
So even though we are getting the categories again from the db to dynamically populate the select list - CI still remembers the users choice from the first time they did the form.
And what about a default category for the drop down? if its not going to change then it can be set as a config. if the category values are coming from a database and they can change - then the default category could be created in the model.
EDIT 2
gosh i always do this anyway so why didnt i think of it for this. so yeah this is yet another reason to make a specific method for showing your view
function _showCategoryForm(){
// get the categoryarray
$data['categoryarray'] = $this->categorymodel->makedropdown() ;
// anything else thats needed for the view
// load form view
$this->load->view( 'myform', $data ); }
NOW we dont have any repeated code, and its easy to customize the validation failure with an error message if needed.
// since i'm grinding on this - the validation should happen in a model
// and that method returns true or false
if ( $this->somemodel->validateCategoryForm() == FALSE ) {
// custom obnoxious error message
$this->formerrormessage = "What part of required is eluding you?" ;
$this->_showCategoryForm() ; }
This is much better because if the needs of your form changes - the change is only in one place. Also i added an underscore to remind us all that private methods are a good practice. And the form validation should be separate in a model, that is called by the controller.
You just need to set it as the default value, for example <input type="text" name="username" value="<?php isset($_POST['username']) echo $username;?>" /> That way, $_POST['username'] will always be available.
How to make array of textbox fields in PHP?
I'm using the CodeIgniter framework.
I'm using the form_input function to make a 2d array of textboxes and pulldowns.
The function produces HTML like this:
<input type="box" name= "variable">
I need to create 30 rows of 5 textboxes (time, event, supplies, sucess{yes/no}, comment).
My plan was to somehow be able to uniquely identify them all so at a later stage when I $Post them to another page it wont get confused as to which textbox is time1 or which textbox is time2.
I'm trying to make this array of texboxes in php so that when I use a for loop with (ISSET) I can stop when I get to a row that is not completed by the user.
This is my code here but im not too sure if its spot on
for ($i =0; $i< 30; $i++)
{
//time part of event field
echo form_input ($events['time',$i]),
//the event itself
form_input ($events['event',$i]),
//supplies used
form_input ($events['supplies',$i]),
//successful?
form_dropdown ($events['success',$i] $success),
//comment if necessary
form_input ($events['time',$i]);
echo '<br/>';
}
I really don't understand either but regarding the $_POST object; this is from the CI docs:
CodeIgniter comes with three helper
functions that let you fetch POST,
COOKIE or SERVER items. The main
advantage of using the provided
functions rather than fetching an item
directly ($_POST['something']) is that
the functions will check to see if the
item is set and return false (boolean)
if not. This lets you conveniently use
data without having to test whether an
item exists first. In other words,
normally you might do something like
this:
if ( ! isset($_POST['something']))
{
$something = FALSE;
}
else
{
$something = $_POST['something'];
}
With CodeIgniter's built in functions
you can simply do this:
$something = $this->input->post('something');
Drupal 6 Validation for Form Callback Function
I have a simple form with a select menu on the node display page. Is there an easy way to validate the form in my callback function? By validation I don't mean anything advanced, just to check that the values actually existed in the form array. For example, without ajax, if my select menu has 3 items and I add a 4th item and try to submit the form, drupal will give an error saying something similar to "an illegal choice was made, please contact the admin."
With ajax this 4th item you created would get saved into the database. So do I have to write validation like
if ($select_item > 0 && $select_item <= 3) {
//insert into db
}
Or is there an easier way that will check that the item actually existed in the form array? I'm hoping there is since without ajax, drupal will not submit the form if it was manipulated. Thanks.
EDIT:
So I basically need this in my callback function?
$form_state = array('storage' => NULL, 'submitted' => FALSE);
$form_build_id = $_POST['form_build_id'];
$form = form_get_cache($form_build_id, $form_state);
$args = $form['#parameters'];
$form_id = array_shift($args);
$form_state['post'] = $form['#post'] = $_POST;
$form['#programmed'] = $form['#redirect'] = FALSE;
drupal_process_form($form_id, $form, $form_state);
To get $_POST['form_build_id'], I sent it as a data param, is that right? Where I use form_get_cache, looks like there is no data. Kind of lost now.
Since you're already using AJAX, why not just write a bit of jQuery to only allow form submission if the choice is within the list of legal choices? This can be done within the custom module it already looks like you're working on (using drupal_add_js()).
It is not especially 'easy', but the standard way to do it would be to use Drupals Forms API for the callback submission as well - that way, you'll get the same validation that would happen on a non js submit. Take a look at Adding dynamic form elements using AHAH. While it does not match your scenario exactly (they rebuild the form on the callback to add new elements, not to save data), the explanation of the processing workflow is pretty helpful. Then there are several modules that try to offer AJAX form submission in a generic way - you could check their code on how to do it (or maybe just use them ;) Ajax submit (only has a dev version) Ajax (has an 'official' release) Finally, there are efforts to put better support this functionality into core in Drupal 7 - the related discussions might also help.
