I just started CodeIgnitor, that's the first time I use MVC structure though, and I have a problem that I've never seen before... It's mainly in the "form" part, but also in the database display.Also I use Xampp.
I've got a form to create an item to insert in the database, but whenever i click the submit button, things gets wrong in the url section.
My base URL is : localhost/CodeIgniter-3.1.1/ (CodeIgniter-3.1.1 is the directory that contain every php folder).
So the form page URL is : localhost/CodeIgniter-3.1.1/index.php/news/create
And when i submit, it is : localhost/CodeIgniter-3.1.1/index.php/news/localhost/CodeIgniter-3.1.1/index.php/news/create
It just repeat the entire URL after the controller (news).
I don't think it has to be with config.php, my base URL seems good, I just don't know.
Make your base url http://localhost/Codeigniter-3.1.1/index.php/ then in your <form> tag set the url like this <form method="post" action="<?= base_url('news/create') ?>">
In /application/config/config.php set $config['base_url'] like this
$config['base_url'] = http://localhost/Codeigniter-3.1.1/
In your view do either one of the following to create the <form> tag
<form method="post" action="<?= base_url('news/create'); ?>">
of if you have loaded the "Form Helper" (documented here) use this line in the view
<?php echo form_open('news/create'); ?>
It's handle by the framework, as so:
<h2><?php echo $title; ?></h2>
<?php echo validation_errors(); ?>
<?php echo form_open('news/create'); ?>
<label for="title">Title</label>
<input type="input" name="title" /><br />
<label for="text">Text</label>
<textarea name="text"></textarea><br />
<input type="submit" name="submit" value="Create news item" />
</form>
Also, the problem occure when I put a link to a view, like :
<a href="<?php echo 'news/'.$news_item['slug']; ?>">
Instead of building the right URL it copy itself along the bar.

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 = $this->input->post('polid');
}
I want to transfer the "polid" from view to controller function using anchor tag.
All positive suggestions are appreciated.
I want to echo something once a form is submitted. But when I click the submit button, it seems that the page is just refreshing itself and I do not see the word that I have written in the echo section. Here is my code:
<?php
if (isset($_POST['submit'])) {
echo "submitted";
}
?>
<h3>Post your form here</h3>
<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<label>Insert a title here</label><br>
<input name="title" type="text" placeholder="add a title"><br><br>
<label>Insert the body here</label><br>
<textarea name="body" placeholder="insert the body here "></textarea><br><br>
<input type="submit" value="submit" name="submit"><br>
</form>
I also tried the code by removing the isset function, but that did not work, either.
In form action, you have missed an echo.
action="<?php echo $_SERVER['PHP_SELF']; ?>"
This is working code. I test it on my Machine.
Why you don't use else statement to test it better.
here is the code.
Note (Check your localhost server settings)
<?php
if (isset($_POST['submit'])) {
echo "submitted";
}
else
{
echo "Not working";
}
?>
<h3>Post your form here</h3>
<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<label>Insert a title here</label><br>
<input name="title" type="text" placeholder="add a title"><br><br>
<label>Insert the body here</label><br>
<textarea name="body" placeholder="insert the body here "></textarea><br>
<br>
<input type="submit" value="submit" name="submit"><br>
</form>
Actually the credit goes to #ashok. He was right that I needed to check localhost server settings.
I am using Phpstorm to write PHP codes. Whenever I click on the Chrome browser to see the results, it takes me to
http://localhost:63342/ name of the file page.
The port 63342 is the default port used by Phpstorm. Since I am using Xampp and it runs on port 8080. I changed port number 63342 to 8080, and it worked.
If you are submitting to the same page, you really dont need to define an action.
Instead of isset, use !empty as such
if(!empty($_POST['submit'])){
echo "success";
}
I must bring to your attention that if the suggestions don't work, you should start with debugging what you are actually receiving from the form POST, using:
<pre>
<?php var_dump($_POST); ?>
</pre>
Turning on error reporting in your php settings is also a good start for debugging.
I am currently in the process of designing a Computer Aided Learning package. The welcome screen simply requires the user to type in their name into a text field and click a button which directs them to 'subject selection' page. How would I go about storing the user input and how, if possible, could I refer to the stored value on a seperate html page?
<div id="inputbox">
<form>
<input type="text" name="field" class="textInput" />
</form>
</div>
<div id="introsubmit">
</div>
HTML:
<div id="inputbox">
<form action="script.php">
<input type="text" name="field" class="textInput" />
</form>
</div>
<div id="introsubmit">
</div>
That will send the form to script.php (if no 'action' defined, it will send the form to the very same page, if that html is inside script.php then it will work the same, and if no "method" is defined, if will use GET, you can set <form action="script.php" method="POST"> to change this):
script.php:
<?php
session_start();
$_SESSION['name'] = $_GET['name'];
?>
and then you reuse that variable in the same session, remember to always invoke session_start() before any output in your php.
It is very difficult for me to put in words my query. But I will try.
I have a site xyz.com which has search facility for listed products. The search page url is generated like this :www.wyz.com/search/search_term
I want to create a iframe page in a third party site with a search facility which can directly communicated with my site xyz.com.
I have tried to create a search box with a submit button. I want to append the search query in as a variable to my form action url string.
So the search string should look like this :www.wyz.com/search/my_string_variable
The code I have written is:
<?php
$url='http://www.xyz.com/search/';
?>
<?php
if (isset($_POST['submit']))
{
$r1=$_POST['num1'];
}
?>
<?php
$result=$url.$r1
?>
<html><body>
<form action="<?php echo $result; ?>" method="post">
Num1:<input name="num1"><br>
<input type="submit" name="submit">
</form>
</body></html>
==================================================================
But output what I get, is only "http://www.xyz.com/search/". It removes my variable from the url. I am not able to find what is the reason? I have also tried to print result via to check the actual output and it shows that it has added the value at the end of url. But when I want to achieve the same thing via form action it does not work. please help?
<?php
$url='http://www.xyz.com/search/';
?>
<?php
if (isset($_POST['submit']))
{
$r1=$_POST['num1'];
$result=$url.$r1;
header("location:$result");
}
?>
<html><body>
<form action="" method="post">
Num1:<input name="num1"><br>
<input type="submit" name="submit">
</form>
</body></html>
Please try the above code. I have made some modifications. The main reason your code is not working is whenever you press the submit button it is going to the the url "http://www.xyz.com/search/" directly .The if condition is never executed. In the above mentioned code it will work properly
action="" - you are submitting to the wrong url. Here is alternate version -
<?php $url='http://www.xyz.com/search/';
if (isset($_POST['submit'])) {
$r1=$_POST['num1']; header("Location: ".$r1); // 302 redirection
}
?>
<html><body> <form target="_SELF" method="post"> Num1:<input name="num1" type="text" /><br /> <input type="submit" name="submit" /> </form> </body></html>
I have an example at the following url, which sends the user to a basic form.
The code for the form is the following;
<?php echo validation_errors(); ?>
<?php echo form_open('form'); ?>
<h5>Username</h5>
<input type="text" name="username" value="" size="50" />
<div><input type="submit" value="Submit" /></div>
</form>
If I understand correctly, once the user presses "submit", it should go back to the controller named "form". But it does not work as expected.
I would want it to submit to index.php/form, and instead it goes to /index.php/index.php/form
Feel free to test out website at url above and see the issue by yourself.
I just looked at your source code and noticed this:
<form action="http://helios.hud.ac.uk/u0862025/CodeIgniter/index.php/index.php/form" method="post" accept-charset="utf-8">
Which displays two "index.php"s. This likely means you have "index.php" set in your base url AND index page configuration. You should remove the "index.php" from one of those sources, preferably from your base_url.
Check your base_url() in config file. If it is correclty, than you can write the form like this:
<?php echo validation_errors(); ?>
<?php echo form_open('controller_name/function_name');
// controller name write your name of controller
// and function name write your function
?>
<h5>Username</h5>
<input type="text" name="username" value="" size="50" />
<div><input type="submit" value="Submit" /></div>
<?php echo form_close(); // don't forget to close correct ?>
I have faced this situation once and the problem was i have included index.php in my base_url in ./application/config/config.php file please check and remove if present. You can also solve your problem by removing index.php from index_page key but it is not a good practice to include index.php in your base_url.
