I'm trying to create a page with a form using ci.
When i submit the form, the controller says that I have no data that's been submitted.
I can't see where my error lies.
Here's the view:
<?php echo validation_errors(); ?>
<?php echo form_open('widgets/search/'.$hardwaremodel.'/'.$objectid.'/'.$name.'/'.$fd); ?>
<div class="form-group">
<label for="search">Last 4 characters of address:</label>
<input type="text" class="form-control" id="searchstring" placeholder="last 4 characters" size="4">
</div>
<button type="submit" class="btn btn-default">Search</button>
<button type="cancel" class="btn btn-default">Cancel</button>
</form>
Once the page renders, the form tag ends up looking like this:
<form action="http://myserver/myciapp/index.php/widgets/search/205406zl/5461/SW-1/SW1net" method="post" accept-charset="utf-8">
The controller:
public function search()
{
$searchstring = $this->input->post(); // form data
var_dump($searchstring);
exit;
}
The results of the var_dump shows:
bool(false)
Thanks
EDIT 1
I haven't posted the entire HTML page that includes the form... but I display some of the fields passed in the URI as headings on the page - just before I create the form. Hope that clarifies...
Would this impact the POST data? Why is that relevant?
Thanks
A few things I'd suggest doing. First is, if you are going to include other variables in the form_open tag, I would add those variables to your controller, and put them in the form_open tag as URI strings. This will allow the form validation to work if you are going to echo out validation errors.
Also, you should be calling a name on the input->post() to get the specific item, (but you don't need to to get all POST data).
Controller:
public function search($hardwaremodel, $objectid, $name, $fd) {
$searchstring = $this->input->post('search_string'); // form data
var_dump($searchstring);
exit;
}
View:
<?php echo form_open('widgets/search/'.$this->uri->segment(3).'/'.$this->uri->segment(4).'/'.$this->uri->segment(5).'/'.$this->uri->segment(6)); ?>
<div class="form-group">
<label for="search">Last 4 characters of address:</label>
<input type="text" class="form-control" id="search string" name="search_string" placeholder="last 4 characters" size="4">
</div>
Form elements are referenced by name attribute which is missiong on input field searchstring.
Add:
name="searchstring"
on your input field.
in this code you have not used name attribute.You use id.
try this one
<input type="text" name="searchstring" value="xyz">

I am working on a project where I need to pass an ID to controller when someone clicks on the link, and open response in new tab.
I googled for solution on this, but couldn't find proper result. I also tried by sending data through URL in anchor tag, but then it gave an error of config.php file, so I reversed the code.
Currently I am using form tag to pass data. Can ye do this using PHP, or will we have to take help of jquery?
Here's View code:
<form class="form-horizontal" method="post" action='<?php echo base_url() . "home/edit_policy"; ?>'>
<div class="form-group">
<input type="hidden" class="form-control" id="polid" name="polid" value="<?php echo $ajax_view_pol_response[0]->polid; ?>">
<div class="col-sm-offset-3 col-sm-3">
<button class="btn btn-primary" id="editpolsubmit">Edit this Policy</button>
</div>
</div>
</font>
This code is from Controller:
public function edit_policy() {
$polid = $this->input->post('polid');
}
I want to transfer the "polid" from view to controller function using anchor tag.
All positive suggestions are appreciated.
A friend asked me add pattern code to prevent typing email ids and phone numbers, on his WP template site.
As i have added the pattern code to the input field, it still accepts email ids and numbers.
So, i figured that may be the form submit php code got some changes needed. but trickily his form tag doesn't have any action tag,. it just have form ID.
I don't know what to do. I just need to make the pattern work in the input field to prevent email id's and numbers.
the code goes as:
<div class="col-xs-12 col-sm-8 col-md-9">
<div class="message-entry">
<form id="message_reply_form">
<div class="form-group" >
<input type="text" autocomplete="off" class="form-control mb-10" placeholder="<?php esc_html_e( 'Your Message', 'extretion' ); ?>" name="reply_message" pattern="^(?!.*([a-zA-Z0-9._%+-]+)#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)).(?:\b\d{10,11}\b)[0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]" >
</div>
<input type="submit" class="btn btn-primary btn-sm reply_message_btn" value="<?php esc_html_e( 'Reply', 'extretion' ); ?>">
</form>
</div>
</div>
Any help is appreciated..

In HTML5, the action attribute is no longer required.

if I remember correctly, it defaults to current page. This is why the form is still submitted.
Have you tried giving a action attribute to your form?
<form action='your/url'>
The body of your form
</form>
I haven't used CodeIgniter in nearly a year and I seem to have forgotten a lot of the fundamentals.
I am trying to retrieve the post variables from a form and pass them into a model which inserts them into mysql.
The controller function my form submits to looks like this:
public function validation() {
$this->load->helper("form");
$this->load->model("contact_form");
$data = array(
"name" => $this->input->post("name"),
... etc. etc. ....
);
if ($this->contact_form->new_form($data)) {
$this->load->view("header");
$this->load->view("submitted");
} else echo "Sorry, there was a problem adding the form to the database.";
}
The form in the view is structured like so:
<? echo form_open("form/validation");?>
<div id="one" style="display: block;">
<h1>A Heading</h1>
<p>Some Text</p>
<p class="bold">Name: <input type="text" name="name" class="single" value="<?php echo set_value('name'); ?>"></p>
<p class="bold">Email: <input type="text" name="email" class="single" value="<?php echo set_value('email'); ?>"></p>
<p class="bold">And then some radio buttons</p>
<p> yes <input type="radio" name="registered" value="yes"> no <input type="radio" name="registered" value="no"></p>
<p class="bold">And a textarea...</p>
<textarea name="description" class="fill" value="<?php echo set_value('description'); ?>"></textarea>
next
</div>
<div id="two" style="display:none;">
<h1>Another Heading...</h1>
<p class="bold">And some more textareas</p>
<textarea name="audience" class="fill"></textarea>
... There are four divs in total with further textarea fields ...
<p class="bold"><input type="submit" name="submit" value="submit" class="center"></p>
back
</div>
<? echo form_close();?>
And finally my model is very simple:
class contact_form extends CI_Model {
public function new_form($data) {
$query = $this->db->insert("contact", $data);
if ($query) {
return true;
} else return false;
}
}
The form processes without any errors, but the data just appears as 0's in MySQL. If at any point I attempt to output the value of $_POST it returns BOOL (false), or with $this->input->post('something'); it returns NULL.
You will notice that no actual validation takes place. Initially I was using $this->form_validation->run() and getting the same results. I thought perhaps I was having trouble with the validation so I stripped it out and now I'm fairly certain my problem is that I'm not passing the $_POST variables correctly.
Can anyone explain why I am failing so hard?
I have now resolved this problem.
For some reason <? echo form_open("form/validation");?> was implementing GET and not POST. Replacing that line with <form method="post" accept-charset="utf-8" action="form/validation"/> resolved the issue.
According to the CodeIgniter documentation, by default, form_open should use POST - I have no idea why in my case it decided to use GET.
I am new with php, but I have already made a registration script that works fine. But the problem is every time I press the submit button to check my error, I'm going to a new page.
My question is how I make that error comes on the same page?
The code I am useing for the html form.
I want the error display in the error div box that I made Any idea ?
<div id="RegistrationFormLayout">
<h1>Registration Page</h1>
<div id="ErrorMessage"></div>
<form action="script/registration.php" method="post">
<label for="Username">Username</label>
<input type="text" name="Regi_username">
<label for="FirstName">FirstName</label>
<input type="text" name="Regi_Firstname">
<label for="LastName">LastName</label>
<input type="text" name="Regi_Lastname">
<label for="EamilAddress">Regi_EmailAddres</label>
<input type="text" name="Regi_EmailAddres">
<label for="Password">Password</label>
<input type="password" name="Regi_password">
<button type="submit" value="Submit" class="Login_button">Login</button>
</form>
</div>
If I understand correctly, you want form validation errors there. This is a very common pattern, and the simple solution is to always set a form's action attribute to the same page that displays the form. This allows you to do the form processing before trying to display the form (if there are $_POST values). If the validation is successful, send a redirect header to the "next step" page (with header()).
The basic pattern looks like this (in very very simplified PHP)
<?php
if(count($_POST)) {
$errors = array();
$username = trim($_POST['Regi_username']);
if(empty($username)) {
$errors[] = 'username is required';
}
if(count($errors) == 0) {
header('Location: success.php');
die();
}
}
<ul class="errors">
<?php foreach($errors as $error) { ?>
<li><?php echo $error;?></li>
<?php } ?>
</ul>
I want to submit this form through PHP. with validation for required field and validation for phone number and email field also
<form action="" method="" id="get-protected">
<div class="row requiredRow">
<label for="txt_FirstName">
First Name</label>
<input id="txt_FirstName" type="text" class="required" title="First Name. This is a required field" />
</div>
<div class="row">
<label for="txt_LastName">
Last Name</label>
<input id="txt_LastName" type="text" title="First Name. This is a required field" />
</div>
<div class="row">
<label for="txt_Phone">
Phone</label>
<input id="txt_Phone" type="text" title="First Name. This is a required field" />
</div>
<div class="row requiredRow">
<label for="txt_Email">
Email</label>
<input id="txt_Email" type="text" class="required" title="Email. This is a required field" />
</div>
<div class="row">
<input type="submit" value="" class="button" />
</div>
</form>
In your method attribute inside your form, you need to declare either post or get.
Since your action attribute is "" it will submit to the page itself rather than redirecting to another page, so you can have your code that checks for validation in the same PHP file. First validation that is often checked is if the variable has a value by using isset:
if(isset($_POST['txt_Phone'])) { ... }
This just checks that the Phone number field does not contain empty data. I strongly suggest you perform other validation checks on the POST array so you do not have any users posting malicious code.
You can use functions like htmlspecialchars to prevent user-supplied text depending on what you plan to do with the values

Form Validation using PHP - PHP and MySQL Tutorial
PHP Advance Form Validation Tutorial
PHP Tutorial Part 2: Form Validation
Your form tag needs a target in the action field and a method in the method field (either GET or POST). So make the action your PHP script.
<form name="input" action="form_submit.php" method="get">
As for field validation, you will either have to parse that inside of the PHP and return a response or use Javascript in the browser to check on the fly.
Here is the shcema of such a script:
if ($_SERVER['REQUEST_METHOD']=='POST') {
//data validation:
$err="";
if (valid_phone($_POST['phone'])) $err="Wrong phone no";
if (!$err) {
//record data:
$sql="...";
query($sql);
Header("Location: ".$_SERVER['REQUEST_URI']); //redirect and exit
exit;
}
}
?>
<html>
<head></head>
<body>
<? if ($err) ?> <font color=red><b><?=$err?></b></font>
<form method="POST" id="get-protected">
here goes your form
Okay, firstly, I like to set the form action to <?=$_SERVER['REQUEST_URI']?> to submit it back to the current page, but leaving it as you have it will work fine too.
Secondly, you need to give all your <input>s a name attribute. This is the variable name that PHP will see.
When your users get an error (something doesn't validate correctly) you don't want all the data they entered to disappear. That means you have to set the value attributes of each input to what they had previously entered. Thus, your form starts to look like this:
<form action="<?=$_SERVER['REQUEST_URI']?>" method="" id="get-protected">
<div class="row requiredRow">
<label for="txt_FirstName">
First Name</label>
<input id="txt_FirstName" type="text" class="required" title="First Name. This is a required field" name="first_name" value="<?=htmlspecialchars($_POST['first_name'])?>" />
</div>
...
<div class="row">
<input type="submit" name="submit" value="" class="button" />
</div>
</form>
If you didn't know <?= is a basically a shortcut for <?php echo but it will only work if your server has short tags enabled. Some people prefer to type it out the long way (in case they want to switch servers later, or for future-compatibility, or because they're nutbars), but I say screw them, I'm lazy.
This page that has the form on it, has to saved with a .php extension (well, technically it doesn't have to, but that's another story). Then you need to handle you form validation. You have to code that up yourself. It might look something like this (put it above your form somewhere)
<?php
if($_POST['submit']) {
$errors = array()
if(empty($_POST['first_name'])) $errors[] = 'please enter your first name';
if(empty($errors)) {
// save the data to database or do whatever you want with it
header('redirect:succcess.php');
} else {
foreach($errors as $e) {
echo $e;
}
}
}
?>
It's been a while since I've coded in PHP so forgive me if there are syntax errors. That's the jist of it anyway, I'm sure you can find validation libraries out there if you Google. Might take some of the grunt work out of trying to validate email addresses and such.
Using Javascript you can do the validation for this form.For each condition you can use return true and return false,based on the condition.Then you can submit the value.
Using action attribute in form tag the values will be submitted to that file.
