$number = $_POST['number'];
$code2 = substr($code, $number);
$strtrfrom = $_POST['strtrfrom'];
$strtrtoo = $_POST['strtrtoo'];
$submit= $_POST['submit'];
if($code == "") echo "";
else {
    if($submit == "Submit") {
       echo "<textarea rows=\"8\" cols=\"50\">\n";

       echo "</textarea>\n";
    }
}
?>

 

Can anyone help?

you never output $number. You use it to set $code2 but then $code2 is never used either.

Soo would this solve it?

 

<form action="index.php" method='post'>
<p>

Code<br />
    <textarea name='code' rows="8" cols="50"></textarea><br>
   
    Number<br />
        <input type="text" name="number" /><br />


    strtrfrom<br />

    <input name="strtrfrom" value="" size="50" type="text" /><br />

strtrtoo<br />

    <input name="strtrtoo" value="" size="50" type="text" /><br />
<br />

    <input type='submit' name='submit' value='Submit'/><br>
</form>
</p>
<?php
$code = $_POST['code'];
$number = $_POST['number'];
$code2 = substr($code, $number);
$strtrfrom = $_POST['strtrfrom'];
$strtrtoo = $_POST['strtrtoo'];
$submit= $_POST['submit'];
if($code == "") echo "";
else {
    if($submit == "Submit") {
       echo "<textarea rows=\"8\" cols=\"50\">\n";
       echo(strtr($code2,$strtrfrom,$strtrtoo));
       echo "</textarea>\n";
    }
}
?>

I can come over and wave my magic wand if you wish. It usually works.

 

No, seriously, what are you trying to do? How can we make it work if we don't know what it's supposed to do?

Sorry Dan, for the bad description, its meant to use php's strtr function. Fill in the form and enter the number to read from and too and when submit is clicked it echos the result.

 

Heres the code with added description:

 

<form action="index.php" method='post'>
<p>

Code<br />
    <textarea name='code' rows="8" cols="50"></textarea><br>
   
    Number<br />
        <input type="text" name="number" /><br />


    strtrfrom<br />

    <input name="strtrfrom" value="" size="50" type="text" /><br />

strtrtoo<br />

    <input name="strtrtoo" value="" size="50" type="text" /><br />
<br />

    <input type='submit' name='submit' value='Submit'/><br>
</form>
</p>
<?php
//the code to the strtr on
$code = $_POST['code'];
//the number to read from
$number = $_POST['number'];
$code2 = substr($code, $number);
//strtrfrom
$strtrfrom = $_POST['strtrfrom'];
//strtrtoo
$strtrtoo = $_POST['strtrtoo'];
//submit
$submit= $_POST['submit'];
if($code == "") echo "";
else {
    if($submit == "Submit") {
//echo result
       echo "<textarea rows=\"8\" cols=\"50\">\n";
       echo(strtr($code2,$strtrfrom,$strtrtoo));
       echo "</textarea>\n";
    }
}
?>

 

Thanks
