PHP POST not working correctly - php

When I submit my form, I get sent to the correct file as specified in the action attribute of my form, but the PHP in the file isn't printing the variables at all... I've combed through posts of other people having the same issue, but none of their solutions fix my problem. I've stripped my code down to a simple, textbox, button, and a php file that's supposed to print the textbox value.
If it matters, I'm running this locally in chrome, not using any servers or websites yet, I'd like to get my code working locally before I upload to my server.
HTML
<html>
<form action="Submit.php" method="post">
<input type="text" placeholder="First Name" name="firstName" id="firstName" required>
</br></br>
<input type="submit" name="submitted" value="Submit">
</form>
</html>
PHP
<html>
<body>
Name <?php echo $_POST["firstName"]; ?><br>
</body>
</html>
All I get when I click the button is a white page with "Name" printed.
Thanks!

Running scripts in response to HTTP requests is something that's done by the webserver. If you just use local files, the script will simply be loaded into the browser as a text or HTML file, it won't be executed. You can't do form processing like this.
You need to run a local server, then access the form as http://localhost/form.html

PHP contact form returning the PHP code when I press the submit button

I created a contact form for my website. When I click the submit button, it just shows the PHP code instead of the message it is supposed to show, like the text information the user inputs into the form.
Here is the HTML code for the form:
<html>
<link href="contact.css" rel="stylesheet" type="text/css" />
<head>
<title>Contact Us</title>
</head>
<body>
<form action="contact.php" method="post">
<div id="ContactForm">
<fieldset>
<h4>Contact Parquest:</h4>
<label class="labelone" for="name">Name:</label>
<input name="name"/>
<label for="email">Email: </label>
<input name="email"email"/>
<label for="commens">Comments: </label>
<textarea name="commens"></textarea>
</fieldset>
<fieldset>
<input class="btn" type="submit" value="Send Email"/>
<input class="btn" type="reset" value="Reset Form"/>
</fieldset>
</form>
</div>
</html>
I couldn't post the PHP code, because it just doesn't show when I try, so here's a screenshot:
There is no problem to your code.. The problem is on your environment.. I guess you are not running the html file through a server..
If the url on your browser looks like these:
file:///c:/path/to/your/file/page.html
then you are doing it wrong.. in order to run .php scripts, you need a web server like apache or nginx... the url of should be like these
http://localhost/path/to/file/page.html
then the php file should run as expected..
php files are interpreted scripting language and thus it needs an interpreter in the server in order to run.. if it is just browsed in the browser without a server, it will just output the code inside..
You need a web server to run php scripts.
Try installing wamp and then run your page under localhost.
I have executed the given code. It's working fine on my local server. Conventionally it should print the value inputs posted by form on contact.php.
But the thing I noticed in your PHP code is the variable name is $commets, instead of $comments.
I faced the same problem and when I tried starting my own server it worked.
when you are using Windows, open cmd and type in this;
php -S localhost:4040;
you will see something like this
PHP 8.1.1 Development Server (http://localhost:4040) started
meaning you have started your own server, then you can copy the link found in the parenthesis
so you copy say this "http://localhost:4040" and paste it in your browser then you can now direct it to your html document like this
http://localhost:4040/Desktop/Projects/index.html
now your form should work well with your php script when you submit
i had the same issue, even if appache & mysql were running on my computer.
in the html file, i wrote :
form action="http://localhost/file.php" method="POST"
instead of :
form action="file.php" method="POST"
It seems like connecting HTML forms to php files only works when you download wampserver and turn on all services...
Here's how it worked for me:
You can download wampserver from here: http://www.wampserver.com/en/ (follow instructions)
I saved it to the C: drive on my computer.
Next, you can create a php file and an html file both in the 'www' folder of the wamp folder in whatever drive you put it in. Copy the form code into the HTML file, and the php code into the php file.
Finally, go to 'localhost/yourhtmlname.html' and fill out the form. It should work as normal.

PHP code being shown in HTML form text fields

I have this code to display PHP value in HTML form text field:
<form method="post" action="">
<input type="text" name="firstname" maxlength="30" value="<?php echo $firstname;?>"><span class="error"> <?php echo $firstnameErr;?></span>
Problem is I see <?php echo $firstname;?> being displayed in the text area instead of the actual user-input name or a blank field.
I tried using <? php echo and <?= and neither work any different, my server supports PHP.
How do I fix this?
i believe what is happening is you're opening the file by double clicking rather than "running" the file by navigating to it in your web browser.
i tested your code and it works fine. however, if i just OPEN the file rather than navigating to it via http, then the php code displays inside the text box.
remember, php (and other server side script types like jsp) have to be run, you can't just open them, or drag them into a browser window to test them.
so if, for example, you're using xampp or apache, you would go place the file inside your htdocs folder, open your web browser, and type something like localhost/plc.php
btw, here is the code as i tested it:
<?php
$firstname = "bob";
$firstnameErr = "phil";
?>
<html>
<head>
</head>
<body>
<form method="post" action="">
<input type="text" name="firstname" maxlength="30" value="<?php echo $firstname;?>"><span class="error"> <?php echo $firstnameErr;?></span></form>
</body>
</html>

Locally testing form handling with PHP

I am creating an online order form for a wholesale nursery. I am trying to test the PHP locally and have successfully set up WAMP. When I test basic scripts, they run just fine but when I try using _POST to send data to variable from HTML input fields, nothing gets transferred to my PHP variables as noted when I try echoing them to a page. Is there something I need to do to test _POST and _GET methods locally that I don't know about?
I tried testing my ability to do so using a simple example I found at W3 schools:
<html>
<body>
<form action="test.php" method="post">
Name: <input type="text" name="fname"><br>
Age: <input type="text" name="age"><br>
<input type="submit">
</form>
</body>
</html>
Here is the PHP:
<html>
<body>
Welcome <?php echo $_POST["fname"]; ?>!<br>
You are <?php echo $_POST["age"]; ?> years old.
</body>
</html>
Like I said, I used WAMP and both files are located in the wamp/www/ folder.
First of all all forms need a method (get, post) and an action (where to send the data) in the html.
<form action='your/location.php' method='post'>
<input type='text' name='username'/>
<input type='submit' value='submit'/>
</form>
All inputs must have a name attribute this is for referencing data in the php script
<input type='text' name='username'/>
In your/location.php you will receive an array with the data under the name:
$_GET or $_POST depending on your method set in the form tag.
To access specific data use $_POST['username'] (replace username with any names set on any of the submitted form inputs)
To print out on the screen use
echo $_POST['username'];
Check if your file is under the extension .php and has the name test
If you get partial output and by partial i mean only the html part start you php server Apache or Nginx or whatever wamp uses, it might not start with all the functionality without specified to do so.
Make sure you open the page under localhost if you are testing it separately.
If for some reason you can't seem to get wamp to work try xampp which is similar and in my opinion better and never failed me.

HTML form action goes to wrong place, doesn't send variables to intended file

so I've been fighting with this for a few days, and I just can't seem to make it work. Whenever I press the submit button, the browser should send the post variables to write.php, but instead, it just redirects back to the website homepage, or the Document Root. This should be really, really simple, and I've done it before, but now it doesn't work for me. What I want to know is if this is a problem with my webserver setup, or PHP, or just a stupid mistake on my part. It's just a simple HTML form, not really special, so here's the form itself, in index.php:
<p style="font-size:13px">
<?php
$rp = fopen('mainlog.txt', 'r');
while(!feof($rp))
{
$read = fgets($rp);
echo($read).('<br/>');
}
fclose($rp);
?>
</p>
<form action="write.php" method="post">
Name: <input type="text" name="user" /><br/>
Changes:<br/>
<textarea cols="70" rows="8" name="change" style="background-color:#555;color:#ccc;font-family:verdana,arial,helvetica,sans-serif;font-size:13px"></textarea><br/>
<input type="submit" value="Add Entry"/>
</form>
And here's where it send to, in write.php:
<?php
$fp = fopen('mainlog.txt', 'a');
$wr1 = $_POST['change'];
#$my_t = getdate(date("g"));
date_default_timezone_set("America/New_York");
$date = date("n").('/').date("d").('/').date("Y").(', ').date("g").(':').date("i").(':').date("s");
$who = $_POST['user'];
$write = $date.(' by ').$who.('
').$wr1.('
');
fwrite($fp, $write);
fclose($fp);
header('Location: http://www.zennixstudios.com/first/chlog/');
?>
I have tried this both on my Apache 2.2 dedicated server with PHP 5 on FreeBSD8.2, and on XAMPP for Windows, with the same results. I have a suspicion that it may have something to do with PHP, specifically PHP include(), because I have several of those on this page, and when I put this on a friend's computer with XAMPP, but without the included files, the include()s just put errors on the screen, but the HTML form suddenly works fine. So, are there any known conflicts with HTML forms and certain PHP functions?
Other Notes:
The code shown above for index.php is within the main page div, but if you want the whole page source just ask.
I'm pretty sure the error isn't in write.php, because I KNOW that the browser never sends anything to it, because it would at least put the date in mainlog.txt.

Here is your problem:
<table align="right"><tr><td align="right"><form action="/" method="post">Username: <input action="login.php" type="text" name="uname"/><br/>Password: <input type="password" name="passwd"/><br/><input type="submit" value="Login" align="right"/></td></tr></table>
You never closed the form up in your header for the username and password, so your <form action="/" method="post"> is being used for pretty much the entire page and your write.php form action is being ignored because a form is already, technically, open. You'll need to close the form in your header for the rest of your page to work properly.
To reiterate: nothing is being redirected, you're actually posting all the data from both 'forms' to the location / as specified.

PHP Script won't load

I'm new to web development and have been wrestling with this problem for several hours now, so I've decided to turn to your wisdom. I'm trying to design a little webpage with a database for my wife to store her recipes in, but I'm having trouble getting form submission to work. Here is the code for the webpage where I take the form information in:
<html><body>
Enter the information below to add a new ingredient for use in your recipes.
<form action="add_to_database.php" method="post">
Name: <input name="name" type="text" />
Serving: <input type="text" name="serving" />
Calories: <input type="text" name="calories" />
<input type="submit" />
</form>
</body></html>
And here is some silly code I've been trying to display on the page to see if I can even get the form submission to work:
<html><body>
<?php
$name = $_POST['name'];
echo $name."<br />";
?>
</body></html>
Unfortunately, the page comes back as completely back (after I hit the submit button). What's absolutely baffling to me is that I've copied and pasted the examples from this page into some files and everything seems to work fine. So it seems as though apache and php are working correctly, but I'm messing up somewhere along the way. My apologies in advance if this seems like a stupid question but for the life of me I can't figure it out.
Do you name the other file as add_to_database.php where the form is submitted. Instead you can test on teh same page by removing the add_to_database.php from the form action.
form action="" method="post">
Name: <input name="name" type="text" />
Serving: <input type="text" name="serving" />
Calories: <input type="text" name="calories" />
<input type="submit" />
</form>
and write the php code on the same page as
$name = $_POST['name'];
echo $name;
If this is not working for you. Create a php file named test.php and type phpinfo(); there.
Verify that your page is indeed being processed by PHP - obvious question, but does your PHP file have a .php extension? Do other things like phpinfo() or echo "Test"; work?
Check the error log in /var/log/apache2/error.log or similar (if on Linux, dunno where that'd be on Windows).
Try turning display_errors on in the PHP configuration (this is a good idea only for a development install, not a production server).
a bit of a longshot, but if you can verify that php is pro essing the page. Clean up your html, you are missing the dtd, head, and encoding. . hard to say how a browser is going to interpret a form (missing a name attribute) without these.
