Well, I need the $i to change value to $i++ with each click on the "Go" button.
That is, I click the button and "1" will appear, when I click again "2" will appear, and so on. How can I do it?
<form method="post">
<input type="submit" name="Submit" value="Go!">
</form>
<?php
$i = 1;
if (isset($_POST["Submit"])){
echo $i;
}
I do not know what your purpose is and I do not know if you really need to use PHP, but anyway I'll post a solution here in javascript, it might give you the result you want ...
<html>
<form id = "formulario">
<input type = "submit" name = "Submit" value = "Go!">
<label id = "resultado">1</label>
</form>
<script type="text/javascript">
var i = 1;
$("#formulario").submit(function(e) {
e.preventDefault();
i++;
$("#resultado").html(i);
});
</script>
I'm using jquery ... stackoverflow does not let you copy all the code, but I hope you understand ...
You can put a hidden field to keep track of the counter and increment it by PHP every POST submission.
<form method="post">
<input type="hidden" name="contador" value="<?php echo isset($_POST['contador']) ? $_POST['contador'] : 1; ?>">
<input type="submit" name="Submit" value="Go!">
</form>
if (isset($_POST["Submit"])){
$_POST['contador']+=1;
echo $_POST['contador'];
}
