Working with Polymer 1.0, I try to implement the iron-form element, when I use the method "GET" it's working, but when I try to make a "POST" about the same file on the same path error occurs 404 not found.
My custom element (contact-form):
<dom-module id="contact-form">
<template>
<div class="horizontal center-center layout">
<link rel="import" href="add.php">
<div>
<div class="horizontal-saction>
<form is="iron-form" id="form" method="post" content-type="application/json" action="add.php">
<paper-input name="name" label="Name" requiered></paper-input>
<br><br>
<paper-button raised onclick="sumitForm()">Submit</paper-button>
</form>
</div>
</div>
</div>
</template>
<script>
function submitForm(){
document.getElementById('form').submit();
}
Polymer({
is:'contact-form',
});
My add.php contains:
<?php
var_dump($_POST['name']);
?>
The file path add.php is elements/contact-form/add.php and 404 not found, when I "POST", occurs on the same path http: //localhost:5000/elements/contact-form/add.php. I do not understand because it happens. Sorry for my English.
Seems to me your server configuration must be doing something different with GET and PUT requests. YOu make no mention of what server you have and how its configured, but first check in dev tools if you have a chrome browser and watch the traffic to and from the server.
EDIT - further update on some thought in this
Submitting the form
<paper-button id="submit" >Submit</paper-button>
Then in your Polymer object
listeners: {'submit.tap':'_submitlogon'},
_submitLogon: function() {
this.$.form.submit();
}
SECOND EDIT.
If you are using gulp serve, then it is using its own web server. This has no ability to run any php code. So probably what is coming back is the raw text of php source code. If its stored in a place where the server can find it. I am wondering how the ajax request is being handled - since it is expecting (specifically in POST mode, so I don't understand how GET worked) a JSON formatted response. Obviously the source of your PHP isn't json, so it won't recognise the format and error out.

I'm trying to execute a shell script from an HTML page using PHP. I have found a previous example here that I have been trying to follow but I'm having an issue. I'm not sure what the cause is but no errors are returned and no file is created from the bash script.
index.php:
<!DOCTYPE html>
<html>
<head>
<style></style>
</head>
<body>
<form action="./test.php">
<input type="submit" value="Open Script">
</form>
</body>
</html>
test.php
<?php
exec("./bash_script.sh");
header('Location: http://local.server.edu/ABC/abc_test/');
?>
bash_script.sh
#!/bin/bash
touch ./test_file.txt
One thing I have noticed that may be the cause of the issue is that it seems the path on the local server doesn't match with the file system exactly.
If I switch all the relative paths in the scripts to absolute paths such as:
/local/sequence/temp/abc_test/file.exe
Then after clicking the button to run the script I get an error saying:
The requested URL /local/sequence/temp/abc_test/test.php was not found on this server
Edit:
The three files They're located at /local/sequence/temp/abc_test And there is a symbolic link pointing to that directory at /export/www/htdocs/ABC
The error message seems to be indicating that test.php is not being found. As written, it needs to be in the same directory as index.php
You’ve tested the actual bash script, so we can proceed with the assumption that it’s in the execution of the script receiving the submission.
I would suggest putting all the web stuff into one page, because you can test sending and receiving input.
<?php
// for testing
// exec("./bash_script.sh");
// check for POST submission (this is not just reading data)
if(isset($_POST['runScript'])) {
// die('Request received');
exec("./bash_script.sh");
// It’s always proper to redirect after post :)
header('Location: http://local.server.edu/ABC/abc_test/');
die;
}
// finished with logic; show form
?>
<!DOCTYPE html>
<html>
<head>
<style></style>
</head>
<body>
<form method="POST">
<input type="submit" name="runScript" value="Open Script">
</form>
</body>
</html>
Note that I added the name attribute to the submit button, and made the form use POST method while submitting to the calling page (no action means submit to yourself).
I’ve also left a few commented actions to aid in debugging if necessary
You may have to adjust the path to the bash script. Currently it’s going to look in the same directory as index.php, which is not something you’d want to do in production.
You will be able to do that somehow, but its always very risky to allow such operations to execute from the php page.
I have read laravel throwing MethodNotAllowedHttpException and I know that this error often appears when one is POSTing to a GET route, but I am really sure that I am POSTing to a POST route.
Also this does work on my locale Homestead version but its not working on my apache production server.
There is nothing in the Laravel log file.
This is the error:
If one takes a closer look there is GET and POST, I am not sure if something is wrong with the request:
This is start of the from from the blade file (I am not using JS, its a pure HTML based form):
<form action='/users/update/' method='post' id='contactForm'>
{{ csrf_field() }}
<h2>
#lang('list.memb_4')
<input type="submit" class="savebutton" id='contactButton' value="#lang('list.default_41')"></h2>
Any suggestion what could cause this error?
I had to change
<form action='/users/update/' method='post' id='contactForm'>
to
<form action='/users/update' method='post' id='contactForm'>
In my web.php file I also use
Route::post('/users/update', 'UserController#update');
I don't know why - but on my test server Homestead this was no problem, but on my production server this is a problem.
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.
My question is should I convert two html pages to php pages, so the called page can access its POSTed parameters, or is there a way for a called html (.html extension) page to access posted parameters?
I've been reading that because posted parameters are server-side there is no way for JavaScript to do this being client side. I've seen nothing about one html page accessing
parameters if that .html page was accessed via a POST.
Here is my calling form. The called form, needs access to TransDesc (below), which is a text field.
<script type="text/javascript" language="JavaScript1.2">
// Check where we came from so that we can go to the right spot when the
// form gets posted from outside of our HTML tree.
var PostURL = '/event.html';
</script>
Enter a Donation Amount
<script type="text/javascript" language="JavaScript1.2">
document.write(
'<form name="InvGenPayDonation"
action="'+PostURL+'"
onsubmit="return validateForm();"
method=POST>');
</script>
<p> $ <input type='text' name='Amount' value="0.00">
</p>
<p>In honor of <span style="color: #FF0000">
<input type='text' name='TransDesc' id='TransDesc' value="" >
</p>
<input type="submit" value="Next"> <br /><br />
A static HTML file cannot access variables that have been POST'ed to it. It can't even know they're there as they're sent to the server in the HTTP request, the server then deals with them and sends the HTML page in the HTTP response. They're 'consumed' before the page is even sent to the client.
You could use GET and access them via JavaScript, or configure Apache to server .html files as PHP files instead though.
In my opinion, php is the easiest way to go, and as far as languages go is pretty easy to learn and pretty intuitive.
You'll have to either convert them to PHP or use GET instead of POST, as GET parameters are accessible through window.location.href
Yes, I would recommend converting the pages to php. If you are set on using HTML files you will have to edit your htaccess file to run HTML pages as php.
You can always use ajax to retrieve and send post and get values.
You can retrieve it with js by creating a php file and access those with ajax from your html files.
I have a simple HTML form, sending a post request to a php script. In IE8, the form only works intermittently - most of the time the PHP script sees an empty $_POST variable.
Here's my code:
<html>
<head>
<title>Post test</title>
</head>
<body style="text-align: center;">
<?php
echo "<pre>".print_r($_POST, TRUE)."</pre>";
?>
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
<input type="text" name="name">
<input type="hidden" name="hidden" value="moo" >
<input type="submit" value="Search" >
</form>
</body>
</html>
Sometimes the print_r gives the response you'd expect (i.e. it's populated with the data from the form), most of the time it's empty.
Not being able to use POST is a bit of a problem for web applications - anyone got any ideas what's going on, and how to fix it?
Thanks everyone for wading in on this one.
It turns out the problem lay in an Apache module I had enabled.
It's a module to allow apache to use Windows authentication to identify a user via their Windows User id - mod_auth_sspi
The effect is caused by a known bug, in the module, but with a simple extra directive this can be worked around, until a fix is added in the next update, as described here:
http://sourceforge.net/projects/mod-auth-sspi/forums/forum/550583/topic/3392037
That sounds very very bizarre. Does it happen in other versions of IE as well?
I can't tell you what the problem is, but here are my suggestions on how to diagnose it:
Print $_REQUEST rather than just $_POST, to see if the data is coming in via another method.
Use a tool like Fiddler or Wireshark to track exactly what is actually being sent by the browser.
Fiddler in particular has been very helpful for me a few times (mainly when debugging Ajax code), and will tell you exactly what was posted by the browser. If your web server is localhost, you can also use Fiddler to track what is received before PHP gets its hands on it. If not, you can use wireshark on the server if you have permissions for installing that sort of thing.
In addition to Fiddler, I would have suggested a browser-based tool like Firebug, but I don't know of one for IE that is good enough (The IE dev toolbar doesn't give you details of request and response data, as far as I know).
I'm suspicious that when the script is telling you that $_POST is empty, you did not actually POST the form. You can check by adding print($_SERVER['REQUEST_METHOD']); after your print_r($_POST);
If you are posting a file some of the time (i.e. with a file input) then make sure you set enctype="multipart/form-data" in your <form> element.
Have you checked the generated html? Is it possible that echo $_SERVER['PHP_SELF'] isn't producing the output you're after, which messes up the form html, which messes up the POST?
