I made an html file called test.html then I navigated to it as "http://site.com/test.html?test1=a" but the textbox stayed blank. Why is this?
Super simple code
<html>
<head>
<title>Test</title>
</head>
<body >
<input type=text name="test1">
</body>
</html>
The file should be a PHP file, so test.php.
Then maybe something like this:
<html>
<head>
<title>Test</title>
</head>
<body>
<input type="text" name="test1" value="<?php echo htmlspecialchars($_GET['test1'], ENT_QUOTES); ?>">
</body>
</html>
The reason it stays blank in your example is because there is no PHP code to put the value into the field. It isn't automatic. Also, on most servers (but not always), a file with an .html extension will not be parsed by PHP.
Also, passing it to the htmlspecialchars function will help prevent cross-site scripting.
HTML is just another file extension to a webserver, it's not going to do any kind of processing unless you've done something to make that so. Would you expect to open http://site.com/foo.txt?contents=helloworld and see "helloworld" in the browser?
I suggest you google up some tutorials (w3schools is usually good for this sort of thing) on PHP, then on "query strings" and how server side scripting works. You should be up and running with basic site scripting pretty fast.
It might be possible to read the URL via javascript and populate the textbox that way if you must use static html.
<html>
<head>
<title>Test</title>
</head>
<body >
<input type=text name="test1" value="<?php echo htmlspecialchars($_GET['test1']);?>">
</body>
</html>

So I'm just dabbling in this and most likely doing it wrong. But it's a proof of concept so I can get the powers that be to get someone to do it right.
I am using a php script for login and for posting variables from forms.
The problem: I am echocing out an html code that includes the css, html, and jquery scripts all in one file. Which is fine for the css and html portion, but the jquery stuff doesn't work.
Is there a way to place the jquery portion in my php script to make it function, or does it need to be split out and referenced/loaded in the html. (I believe that is the correct way, but I don't know how or where to start.)
code: (after binding to ldap and authenticating, this block is triggered)
// verify binding
if ($ldap_bind) {
echo "
<head>
<link - stylesheet \link>
</head>
<form class=\"form-horizontal\" action\"form.php\" method=\"POST\" enctype=\"multipart/form-data\">
<fieldset>
<body>
html code....lots of div boxes
<script src=\"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js\"></script>
<script>
$(document).ready(function(){
Various Jquery functions that hide/unhide div boxes
});
</script>
</body>
</fieldset>
</form>
";
} else {
echo "<p class='text-error'>Unable to log you in:</p>";
First, your HTML structure is quite mixed up. Have a look at how I "reorganized" it below and feel free to read tutorials like this one about it.
Second, you can use the PHP tags (<?php and ?>) to avoid the multi-line echo and all the quote escaping mess. What is outside these tags won't be processed by PHP and sent as-is to the browser. So you can write "usual" HTML there.
Third, having your scripts outside HTML like <form> is a good practice. And the library calls commonly are placed in the <head>... But it's also common to have it near the end of the document, just above </html>, instead of the <head>. For sure, not oddly everywhere in the markup.
// verify binding
if ($ldap_bind) {
?>
<head>
<title>My page title</title>
<link rel="stylesheet" href="...">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<form class="form-horizontal" action="form.php" method="POST" enctype="multipart/form-data">
<fieldset>
html code....lots of div boxes
</fieldset>
</form>
<script>
$(document).ready(function(){
//Various jQuery functions that hide/unhide div boxes
});
</script>
</body>
<?php
} else {
?>
<p class='text-error'>Unable to log you in:</p>
I'm just following w3schools like a normal person
For me getting php to work is harder than learning the language itself...
If somebody could please provide an extensive guide on common problems such as this one that would be heavily resourceful
I'd also like to know the ins and outs of running php scripts within an html context, not having the php extension on the browser would be preferred in most cases
I can't get the following script to run upon submitting the form. It ends up opening up a window asking me which program should be used to run the php file.
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form action="welcome.php" method="get">
Name: <input type="text" name="name"> <br>
E-mail: <input type="text" name="email"> <br>
<input type="submit">
</body>
</form>
Opening the php file using firefox accomplishes the same thing.
If so, which program should I use? or do I need to update some configuration
in order to get this simple script to work
<html>
<body>
Welcome <?php echo $_POST["name"]; ?><br>
Your email address is: <?php echo $_POST["email"]; ?>
</body>
</html>
One of the easiest ways to get PHP up and running for a newbie would be to use XAMPP. See this Wikihow article on how to get that done: https://www.wikihow.com/Set-up-a-Personal-Web-Server-with-XAMPP
Good luck!
Fairly new to PHP. Have been trying a simple program to get data from 2 fields and display it using GET method.
Heres the HTML code
<html>
<head>
<title>Simple Form</title>
</head>
<body>
<form action="send.php" method="get" id="sample">
Name:<input type="text" name="user"/>
Message:<input type="text" name="message"/>
<input type="submit"/>
</form>
</body>
</html>
Heres the PHP code:
<html>
<body>
Welcome <?php echo $_GET["user"]; ?>
Message <?php echo $_GET["message"]; ?>
</body>
</html>
The GET method fetches the data as a QueryString in address bar of browser, but doesn't display anything in browser window.
The code works perfectly. Reinstalling WAMP server solved the issue.
You need to start the server.
Go to your directory where the index.html file of your website lives, then run the command line php -S localhost:5000.
5000 is the port where php is listening to, you can put any value there....
Install php if you haven't.. Or Wamp

Thanks for answering,
problem is that ,data send is not included after response of sever
please help me as fast as possible
I can only speak for my own experience, but this works on my server. I'd suggest, then, that one of the following is true:
Your server isn't set up to handle php (though this would surprise me), also, as #gAMBOOKa noted (in the comments), if your server's not set up to handle php the script wouldn't output anything other than the raw text-contents of the php script, literally "<?php echo $_POST["data"];?>".
You're trying to access the pages through the filesystem (file:///path/to/file.html), rather than through your server (http://localhost/file.html).
If '2' is correct, move your web-page and php script into a directory within your server's document root, on *nix this could be something like /var/www/directoryName/ and access the page via http://localhost/directoryName/dataEntryForm.html. If you're on Windows, with IIS it could be C:\inetPub\directoryName\ accessed, as above, with http://localhost/directoryName/dataEntryForm.html.
Incidentally, please forgive me for not linking to a demo of the page running, it's just that I'd prefer not to run the risk of exposing my server to, presumably, vulnerable scripts.
Your full code is like this and I tested it, working perfectly.

Below is my piece of code , on giving the tool name as the input and pressing submit , the batch file corresponding to that tool shall be executed.
<html>
<head>
<title>My Form</title>
</head>
<body>
<form action="batch.php" method=post>
Which tool you would like to use:
<br> <input type="text" name="ToolName">
<p>
<input type="submit" name="submit" value="Please wait!">
</form>
</body>
</html>
BATCH.php
<html>
<head>
<title>Perv!</title>
</head>
<?php
$ToolName = $_REQUEST['ToolName'] ;
?>
<p>
Hi <?php print $ToolName;
//exec("cmd/c D:\workspace\execute.bat");
exec("C:\\wamp\\www\\test.bat");
//system("test.bat");
//system("cmd /c D:\\workspace\\execute.bat");
?>
</body>
</html>
I am using Apache /Windows.
Please suggest any help will be appreciated.
As I already commented, what you describe seems to be a problem of your batch file. But anyway, is this file supposed to just do something or to output stuff that should be displayed?
If the later is the case, note that exec() only returns the last line of the output. You can get all the output be providing another variable to get all the output. The official php documentation of the exec() function tells you have to do this.
as far as i could understand your question, you can try this:
system($ToolName);
You may want to specify correct path for the $ToolName variable.
