I am trying to create a form in HTMl. However, I don't know how to make the action attribute work. Below I have attached my code. The form appears, but when I enter the information, it isn't added to the PHP file.
<form action="info.php">
<p>Username:
<input type="text" name="username" size="15" maxlegnth="30" />
</p>
</form>
Another question. When I'm linking things (images, videos, etc.) to my website, do I need to attach the whole link (file:///C:/Users/Name/Desktop/Web%20Developement%20Code/notes.php) or is notes.php enough?
Thank you!
You need to set method="post" to form, and add submit button, then you will be able to get your information.
<form method="post" action="info.php">
<p>Username:
<input type="text" name="username" size="15" maxlegnth="30" />
</p>
<p><input type="submit"></p>
</form>
Then in info.php:
<?php
$username = $_POST['username'];
echo($username) //or any other actions with this variable
In response to your second question, you don't need to provide the full path. It is enough to specify the path from the root folder of your project.

I have a smarty project, and in the .tpl file, there is a form:
<form method="get" action="{$smarty.server.PHP_SELF}?action=func1">
<input type="text" name="username"/>
<input type="submit">
</form>
there is a question, if the php file have many function for different action requests, so in the template if have many forms, I want to through the action for distinguish.
but in my practice, see upper code, I write like this, this can not delivery the action to my php file.
I want to write the action in the form action, because this can be more standard. so I don't want to write it in a hidden input. why write in the action can not pass into the php file?
You could use submit button with specified name and value:
<form method="get" action="{$smarty.server.PHP_SELF}">
<input type="text" name="username" />
<input type="submit" name="action" value="func1" />
</form>
and then you'll get a global variable $_POST['action'] with value func1. But the value will be showing on your button title, so I offer you to find forms only by submit name, for example name='submit_form1'.
I am attemping to create a PHP login system using MySQLi.
However I have created an HTML Form:
<form action="register_manager.php" method="post">
<p>Please fill all fields!</p>
<input type="text" name="username" value="<?PHP print $getuser; ?>" maxlength="15" /><br />
<input type="password" name="password" placeholder="Password" maxlength="15" />
<input type="password" name="confirmpassword" placeholder="Confirm Password" /><br />
<input type="text" name="email" placeholder="E-Mail Address" />
<p style="margin: 0; padding: 0;">
(Use a vaid a valid E-Mail Address for activation!)
</p>
<p>
Already got an account?
</p>
<input type="submit" name="regsubmit" value="Register"/><br />
<?PHP echo '<p>'.$errormsg.'</p>'; ?>
</form>
Once I click submit, it redirects me to the registration_manager.php page, which is not what I want it to do. I am new to PHP so I am not aware on why it is doing this, instead of registering the user.
This is the register_manager.php file:
http://pastebin.com/cvbA6L6P
The action specified in your form is register_manager.php so whenever you hit the submit button you will get redirected there. Also, in the link you provided of the source code of register_manager.php, you're generating error messages, depending on the case, but never printing them on the page so the user can see what is wrong, unless of course the html form you provided is included in the register_manager.php. Finally, when testing make sure you fill all the requirements set by the if statements in you register_manager.php file, i.e. pass all wanted fields (username, email (which must be longer than 7 chars, containing the '#' and '.' characters), password, password confirmation). Hope this solves your question!
What you are describing is normal. The browser will send a POST request to the URL defined as action. So you need to render the form there as well. You can either abstract the form out and reuse it in both files or do the initial form rendering and the processing in one file by checking if $_POST['regsubmit'] is set (if it is not set you are rendering the form initially).
Submit button will activate the request of the webpage specified in the attribute action, passing the information inside the form by the method selected. In your example, the information is passed to register_manager.php using POST method.
To retrieve the information passed, you could use the arrays $_POST and $_GET depending the method used. In your example:
<?php
print $_POST['password'];
print $_POST['confirmpassword'];
print $_POST['email'];
?>
I have a registration form. If a user fill out all the required fields.
And when he reloads the page with out submitting form, the fields contain the values entered by the user. I want them to be empty as they were on first page load.
I have given value="" to the fields but they still contain the previously entered values.
<form id="registration_form" name="registration_form" method="post">
<input name="first_name" id="first_name" value="">
<input name="last_name" id="last_name" value="">
<input name="user_email" id="user_email" value="">
<input name="status" id="status" type="hidden" value="active">
</form>
This is form auto-fill, not page caching. You can disable autocomplete with:
<form id="registration_form" name="registration_form" method="post" autocomplete="off">
Remember to add autocomplete="off" to your form. This is auto-complete issue with some browsers, then you need to use id trick, every time you're loading the registration page, let say:
http://localhost/register.php
you can try it manually to see if it's works for browsers you've been testing, for example load this address on your browser and see if it still auto complete the form:
http://localhost/register.php?id=23
you can add id=anynumber, this happens to work perfectly, I do this with my CSS imports. To make it more PHP you can write some code like this:
$number = rand(1,100);
header("Location: register.php?id=$number");
Hope it helps
If you want to remove cache as you asked first (before edit), There are many ways,
Adding meta tag on page
<meta http-equiv="Cache-control" content="no-cache">
By redirecting using javascript,
window.location.href+'?eraseCache=true';
These are discussed in an other topic here.
If you just want to delete the values on the fields,
use
document.getElementById('text_box_id').value="";
on the top inside the head tag.
I am using this code to make a upload-form for my website.
Youtubeuploader
It works perfect, but I got ONE problem.
I want a form to define the title.
Right now, all the videos are given the title "Example"
I want the user to write their own title for their video.
I've tried making a input with id and name "title", and tried to use $_POST['title'], but it didn't work. The video didn't even upload.
Anyone knows how to do this?
I've looked at all the YouTube Data API code and tried everything.
Thanks.
Given the link you posted, you have to give $youtube_video_title the value from your form.
I mean like this (not secure, always sanitize and filter):
$youtube_video_title = $_POST['title'];
UPDATE :
try to replace the form code with this one
<form action="<?php echo($response->url); ?>?nexturl=<?php echo(urlencode($nexturl)); ?>" method="post" enctype="multipart/form-data" onsubmit="return checkForFile();">
Title : <input id="title" type="text" name="title"/>
<input id="file" type="file" name="file"/>
<div id="errMsg" style="display:none;color:red">
You need to specify a file.
</div>
<input type="hidden" name="token" value="<?php echo($response->token); ?>"/>
<input type="submit" value="go" />
</form>
I would like to make a button on my website that automatically logs me in on another website. I recon I can use either Javascript/jQuery or PHP/cURL to do this.
Which is the best way to go?
You may use either remote javascript or iFrame. Find more details here: http://kuza55.blogspot.com/2007/06/building-secure-single-sign-on-systems.html
Also checkout google's approach named SAML: http://code.google.com/googleapps/domain/sso/saml_reference_implementation.html
It depends what the website is. JavaScript and jQuery alone cannot be used due to the cross-domain policy. You could perhaps use a combination of cURL and AJAX to achieve something similar.
I think you might need to provide a little more information about the site, and exactly why you'd want to do this...
I'm not sure if this is exactly what you're looking for, but one thing I have done in the past is to mimic the login form on the site you want to log in to.
For example lets say you want to log in to 'example.com'. In the source code for the login page of 'example.com' you will find the html code for the login form.
Example
<form name="blabla" action="action.php" method="post">
<input type="text" name="username" />
<input type="password" name="password" />
<input type="sumbit" value="Login" />
</form>
Create a form on your site similar to the one you find in 'example.com'. If you want you can even hide the fields, include values to make it a one button login. The trick is making sure that the action has the actual url. For example if the form says 'action.php' for 'example.com' you would put 'http://example.com/action.php'
Example
<form name="blabla" action="http://example.com/action.php" method="post">
<input type="hidden" name="username" value="testuser" />
<input type="hidden" name="password" value="testpass" />
<input type="sumbit" value="Login" />
<form>
This will log you in to the site in most cases. If you don't want to leave your own site you can set a 'target' for the form to an iframe or something.
