Re: Get Variables values

When you setup the textbox fields, make sure they both have names and that their names are unique. So something like below is an example:

html Syntax (Toggle Plain Text)
<form method='post'>
<input type='text' name='box1' size=30><br>
<input type='text' name='box2' size=30>
</form>
<form method='post'>
<input type='text' name='box1' size=30><br>
<input type='text' name='box2' size=30>
</form>

Then to retrieve those 2 fields and display them you would use the following php code:

php Syntax (Toggle Plain Text)
echo $_POST['box1']; //displays first field in above example
echo "<br>"; // adds new html line.
echo $_POST['box2']; //displays second field in above example
echo $_POST['box1']; //displays first field in above example
echo "<br>"; // adds new html line.
echo $_POST['box2']; //displays second field in above example

So try to make sure the field names are unique and in the form element it has method=post

Re: Get Variables values

I have just done a few tests and I don't see how it is possible to have the two name= fields exactly identicle but what you can do is put arrays in the name= fields and retrieve the $_POST as a 2 dimensional array. Below is an example of what I have done.

php Syntax (Toggle Plain Text)
<form method='post'>
<input type='text' name='test[0]' value='111'><br>
<input type='text' name='test[1]' value='222'><input type=submit value='submit'></form><br>
<?
var_dump($_POST); //dumps the variable
echo "<p><hr>";
echo $_POST['test'][0];
echo "<br>";
echo $_POST['test'][1];
?>
<form method='post'>
<input type='text' name='test[0]' value='111'><br>
<input type='text' name='test[1]' value='222'><input type=submit value='submit'></form><br>
<?
var_dump($_POST); //dumps the variable
echo "<p><hr>";
echo $_POST['test'][0];
echo "<br>";
echo $_POST['test'][1];
?>

Also you need to click the submit button for the above example to work. The above example shows about displaying what information the $_POST array holds and shows about using 2 dimensional $_POST arrays. Other than using arrays in the name= field,or changing the name of the field to be unique, you will find that only the last field of its duplicate name will be recorded in php.

Re: Get Variables values

well I found the way to solve this issue:

php Syntax (Toggle Plain Text)
<form method='post'>
 
	<input name="test[]" type="text" />
	<input name="test[]" type="text" />  
<br>
	<input type=submit value=submit>
</form>
 
<?   
    echo $test[0]."<br>".$test[1]; 
?>
<form method='post'>

	<input name="test[]" type="text" />
	<input name="test[]" type="text" />  
<br>
	<input type=submit value=submit>
</form>

<?   
    echo $test[0]."<br>".$test[1]; 
?>
