Hi,
I'm trying to code a PHP page with a textfield, a button and one link, every time I click in the button the value is added(sum) to a variable and when I click the link I can see the value of this variable somewhere in the page.
please help!
many thanks!!!
This sounds like a job for javascript.
Show us your code so far.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title></title>
</head>
<form action="index.php" method="POST">
<input type="text" name="input_value">
<input type="submit" name="submit">
<body>
<?php
if (isset($_POST['submit'])) {
$formvalue = $_POST['input_value'];
}
?>
</body>
</html>OK, I just need to know how to run a code when I click a link.
its not working... (the sum) whats wrong?
<form action="index.php" method="POST">
<input type="text" name="value_enter">
<input type="submit" name="submit">
<p> </p>
<body>
<?php
if (isset($_POST['submit'])) {
$value = $_POST['value_enter'];
if ($value== 1){
@$a = $a +1;
}
echo @$a;
}
?>I'm trying to code a PHP page with a textfield, a button and one link, every time I click in the button the value is added(sum) to a variable and when I click the link I can see the value of this variable somewhere in the page.
can anyone do this code please?
Didn't anybody tell you patience is a virtue? 3 successive posts in just over an hour? That's a sure fire way of getting ignored.
Anyway:
<form action="index.php" method="POST">
<input type="text" name="value_enter" />
<input type="submit" name="submit" value="Send" />
<p> </p>
<body>
<?php
if (isset($_POST['submit'])) {
$a = 0;
$value = $_POST['value_enter'];
if ($value== 1){
$a = $a + 1;
}
echo $a;
}
?>Anyway, your $a variable needs an initial value if you intend to add something to it.

Thank your for your reply.
it still doesn't work, I keep entering 1 in the textfield and the value doesn't increase...
Do you want a variable that remembers the last value? You can't do as above for an incrementer. You'll probably need to use a session variable or a cookie as web pages are stateless - they don't have a memory.
Or you could keep the running value in a form field - e.g. disabled textbox or a hidden field.
thank you I'm reading about cookies and session variable, I think I can go on from now... bye
