PHP - Piece Of Cake

Hi there,

Sorry if this is the wrong forum to post this in, If it is please feel free to move it to the correct one.

I have a php page and I am trying to get a couple of lines to only be run if Javascript is disabled on the visitors browsers.

Code: [Select]
$returnpage = 'myphppage.php';
include('anotherphppage.php');
It is something probably simple but I can't see it...
I have tried:
Code: [Select]
<noscript>
<?php
$returnpage = 'myphppage.php';
include('anotherphppage.php');
?>
</noscript>
but that does not seem to work and I was hoping someone here would have an idea...

Many thanks in advance

Hello,

I have a variable that holds a piece of text that looks something like this: "world,blue,big".

Is there anyway to split the text into the separate words as an array, and remove the commas?

Code: [Select]
$text_to_split = "world,blue,big";
$splitArray = array();

//Do some kind of php function that splits text\\

echo splitArray[0]; // world
echo splitArray[1]; //blue
echo splitArray[2]; //big

Would appreciate it, thanks

Hi there, i have an code

I read this and I totally not understand what it for and how it use and what problem hidden here.
 

Please help!
 

Hi guys,
I apologize for the number of posts regarding this particular class that I am writing (really, at this point, you've probably done more in it), but I have another issue. I've decided to re-write the pieces that were giving me trouble, and instead of using a for loop, I went to a foreach loop.

Here's what it in the database for the particular query:


Here's what I get when I dump the array with print_r():
Array (
    => Array ( [0] => 4
        [id] => 4
        [1] => Test
        [label] => Test
        [2] => ?r=test
        [link] => ?r=test
        [3] =>
        [relation] =>
        [4] => 0
        [parent] => 0
        [5] => 5
        [sort] => 5
        [6] => 1
        [active] => 1 )
    [1] => Array (
        => 2 [id] => 2
        [1] => About Us
        [label] => About Us
        [2] => ?r=about
        [link] => ?r=about
        [3] =>
        [relation] =>
        [4] => 0
        [parent] => 0
        [5] => 10
        [sort] => 10 [6] => 0
        [active] => 0 )
    [2] => Array (
        => 3 [id] => 3 [1] => Fleet
        [label] => Fleet
        [2] => ?r=about/fleet
        [link] => ?r=about/fleet
        [3] =>
        [relation] =>
        [4] => 2
        [parent] => 2
        [5] => 0
        [sort] => 0
        [6] => 0
        [active] => 0 ) )

And the SQL statement:
SELECT * FROM `menu` ORDER BY `parent` ASC, `sort` ASC

With the corresponding PHP code (The issue starts in formatMenuItems()):
Code: [Select]
<?php

I have this little code that I cannot get to work
Code: [Select]
$sql_buildings = ("SELECT castle, treasury, huts, [b]leader_id[/b] FROM teams WHERE team_id=[b]".$_GET['t']." [/b]");
$rsbuildings = mysql_query($sql_buildings);

if($rsbuildings[".$_GET['t']."] == 'leader_id' ){
The problem is this part:
Code: [Select]
if($rsbuildings[[b]".$_GET['t']."[/b]] == '[b]leader_id[/b]' ){
How can I write it to have these to values work?

I am past a beginner in php but no where near an expert and I need some help. This piece of code he

 $query .= " limit $s,$limit";
  $result = mysql_query($query) or die("Couldn't execute query");

is part of my search results page with paged indexes (next, previous 10, etc.). However with this code i get the die message but if i take the first line off ($query), the page executes but then the page doesn't operate correctly i.e. shows 15 results when the $limit(limit for rows) =10. Is it not written correctly or am I missing somethingwith the top line?

if the entire script is needed let me know and i will paste it? Thanks in advance for any help!

Hi,

I'm just trying out some basic code and playing around with passing variables by reference and i was reading this on the php manual at this page http://php.net/manual/en/language.references.pass.php :


No other expressions should be passed by reference, as the result is undefined. For example, the following examples of passing by reference are invalid:

<?php
function foo(&$var)
{
    $var++;
}
function bar() // Note the missing &
{
    $a = 5;
    return $a;
}
foo(bar()); // Produces fatal error since PHP 5.0.5

foo($a = 5); // Expression, not variable
foo(5); // Produces fatal error
?>


So, i decided to try it out myself like i always do, and i noticed that i'm not getting an error when i do foo(bar()); i.e calling bar() without the & in the function declaration. Infact it works perfectly fine and returns an incremented $a after its passed to foo(). Likewise foo($a = 5); also works great and returns an incremented $a after being passed to foo(). Is this  a mistake in the manual or am i missing something?

Running PHP 5.3.2-1ubuntu4.5

Hi,

I am trying to translate a page in PHP using Google API. There is 5000 chars limit on data that you can send to Google at a time. So I am trying to break the page into pieces of 5000 chars. But as you know while doing this we have to keep in mind the HTML formatting that it should not be disturbed otherwise you will not get desired results.

For example you have to send this:

<a href="#" class="myclass">Link</a>

Instead of this:

<a href="#" class="myclas

I am able to solve it somehow (although not perfectly I guess) by checking if "<" sign is coming after ">" sign or not. If "<" sign is coming after ">" then I go back to the point where I found ">" and cut string from there.

Anyway the point is I am still having some problems regarding HTML formatting and want to know how to do it efficiently. Is there any parser available that will solve this problem!?

Thanks

I’m trying to construct a button that simply writes an "aleph" character into a text area, see below. My code does not work, can anyone tell me why ? How should I fix it ?

<!DOCTYPE html>

{

  theArea.value += '' + text + '';;
 
}            
</script>
</head>
