Parse errors?

PHP Code:

<html> <form method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>" <input type="hidden" name="send" value="1"> <p>Name1<input type="text" name="Name1" /></p> <p>Name2<input type="text" name="Name2" /></p> <p>Name3<input type="text" name="Name3" /></p> <p>Name4<input type="text" name="Name4" /></p> <p>Name5<input type="text" name="Name5" /></p> <p> <input type = "Submit" name = "Submit"/><p> </form> <?php If($_POST[send] == "1"){ $Number = 1; While($Number < 5){ If($_POST[$Number] <> ""){ echo($_POST['Name'[$Number]); $Number++ } } </html>

right here is the error:

PHP Code:

If($_POST[$Number] <> ""){ echo($_POST['Name'[$Number]); $Number++

anyone know?

Re: Parse errors?

u mistook the "["... make it "."

if you wanted to concatenate 'Name' with $ number... and get the result from post

Re: Parse errors?

Re: Parse errors?

Remember, this isn't VB :D

As well as the two errors oceane pointed out, there is also no operator "<>" in PHP. You instead need to use "!=". If you are using an array withing an array you need to make sure you use square brakets to open and close:

PHP Code:

if($_POST[$Number] != ""){ echo($_POST['Name'][$Number]); $Number++; }

Re: Parse errors?

hey visualAd is this fine or is there something wrong with it as well?

PHP Code:

if ($blnRtnFlg == false){ // エラー時 return false; }

what about the === operator? what's their difference?

Re: Parse errors?

I have yet another question

can i do this in php

if(astring != astring)

It seems that is what |23M!x is doing... checking if a string is empty.. somehow I can't find that in the dox.. so I don't do that instead just use.. strcmp...
but just wondering if that's really possible and they just did not document that in string operators part of the dox

Re: Parse errors?

if(astring != astring)

That's a constant false. You can use empty() or just compare against "".

Re: Parse errors?

Yes you can comapre two strings, the comaprison is case sensitive though. If you want a case insensitive comparision you can either convert it to lowercase/uppcase first or use stricmp().

The difference between == and === is on checks for equality and the other checks for equality and type (i.e: are they identical).

PHP Code:

$bool = true; $int = 1; $bool == 1; // returns true $bool === 1; // returns false because $bool is a boolean, not an integer $int == true; // returns true $int === true; // returns false because $int is not a boolean its an integer $int === 1; // returns true $bool === true; // returns true

sorry wrong example. :( It should have been another string...

*sigh*

I should have known better. :( and I could have saved some trouble converting some... :(

Re: Parse errors?

Almost there. thanks alot:

PHP Code:

<?php If($_POST[send] == "1"){ $Number = 1; While($Number < 5){ If($_POST[$Number] != ""){ echo($_POST['Name'][$Number]); $Number++; } } ?>

results in a parse error also. I cannot see anything wrong at all here...

Re: Parse errors?

1.is that okey.. your send... Correct me if I'm wrong, but send there in your first if... would look for a constant variable... :( which is probably empty....

2.then perhaps the case of your if...

3.and where's the closing bracket for your first if?

Re: Parse errors?

$_POST[send]

Re: Parse errors?

I forgot to mention while too... perhaps that would cause some. :)

Re: Parse errors?

You haven't added the last curly bracket "}"
