hi all,

I am new to php. I want to passe data from html page to php file.

here is the code of createComment.html

    <form action="commentSave.php" method="POST">
       <label>Name</label> <input type="text" name="name" value="" /><br>
       <label>Email</label><input type="text" name="email" value="" /><br>
    <label> Website</label><input type="text" name="web" value="" /><br>
        <?php
        echo $var="menuka";
        ?>
   <textarea id="markItUp" cols="80" rows="20" name="comment">

</textarea>

    <input type="submit" value="Submit" />
    </form>

what I tried was print the value of $var in the commentsave.php file

i got all the other values except $var.

i am trying this because I am developing a blog where i want to reply administrator's thread. so i get the thread ID of the thread and passe it with the form data of comments. so that i can read it back properly i.e thread and relevant comments from the data base.
that is why i am asking how to pass the value of $var to php file....
I think you can understand me. please somebody help me.

thanks in advance,
menuka

line 5 - 7 of the HTML file are just text. text is not passed to PHP (why should it?) only form values (like those from <input> and <textarea>).

You can place the value in a hidden input field.

<input type="hidden" name="id" value="your_value" />

thx all it works.

i have to clear how if u want to pass value of id in a php file which taken from database to another page using

<a href="Blog/createComments.php"/>


or if i have more variable such as $var1 , $var2 ,$var3 then how can i pass it to another php file


thx inadvace menuka

[codeprada]

If you're passing values from one PHP file to another then use a SESSION.

[menukadevinda]

is there any option other than session.

Is there any option to pases values via the URL because i get values from the database to the variable . therefore i think session is not good for that.

thx in advance,

menuka

You could also pass it via the URL provided using GET requests. Just make sure it's not super secure or important variables that you pass via GET requests.

You can do things like this:

<a href="page.php?var1=val1&amp;var2=val2&amp;var3=val3">Linkage</a>

Which would link you to a page with the URL:
- page.php?var1=val1&var2=val2&var3=val3

This is what we call GET variables. In the page.php code you could fetch the GET values using the $_GET array.

<?php
echo $_GET['var1']; // == "val1"
echo $_GET['var2']; // == "val2"
echo $_GET['var3']; // == "val3"
?>

Yes, you use GET requests.

Link to learn all about them:
http://www.w3schools...PHP/php_get.asp

Hope this helps

hi all,

<?php
$val1=$row['postId'];
          echo '<a href="Blog/createComments.php?var1=val1;">'.'leave comment'.'</a>'.'<br>';
?>

here is the code

and i got this result
value of var isval1

it is obvious i want not the val1 but the value of $val1 variable.

i think u can understand me.

thx in advance,

w3schools.com said:

The built-in $_GET function is used to collect values in a form with method="get"

Hmmm... $_GET is not a function, it's an array; a super-global. Also, this gives the impression that you need a form to use GET, which isn't true.

This is why I've stopped linking to W3Schools. They tend to have misleading, if not flat out wrong, info.

Better to just link to the PHP manual

It's obvious to us, but if you want PHP to use the variable $val1, you need to include the $ char. Without it, PHP will just read val1 as a normal string.

If you want to inject a variable into a string, you have two options.

First, to end the string, concat it with the variable, and then reopen the string to add the rest.

$val1 = "Hello";
$str = 'Value of val1 is ' . $val1 . '.';
// Value of val1 is Hello.

Or to use double-quotes, and just put the variable into the string.

$val1 = "Hello";
$str = "Value of val1 is $val1.";
// Value of val1 is Hello.

NOTE! These must be double-quotes ("..."), not single-quotes ('...'). PHP does not look for variables inside single-quoted strings.

still i get the same result.

here is the full code.

did I mention that PHP code inside a HTML file is just text and is not interpreted by PHP? (unless you have configured your webserver to feed every HTML file, may it contain PHP code or not, to the PHP interpreter)
