[creating admin area]

just make sure you have $id defined on the pages that need it

[Failing to rename/move image]

Try checking if the folder you're trying to move exists

 

if(is_dir("/new/folder/where/file/is/to/be/stores")){
//rename
}else {
//fail
}

[Help with a form]

well that's the only option i thought of

[creating admin area]

if($id == 1){
echo "<a href=\"/admin/index.php\">Admin Index</a>\n";
}

 

// admin/index.php
if($id != 1){
echo "You are not an admin and cannot be here!\n";
}else {
echo "Welcome runnerjp!\n";
}

[Failing to rename/move image]

Well try using file_exists before trying to move the first file

 

$file = "/home/you/public_html/temp/".$_POST['user']."/file.jpg";

if(file_exists($file)){
   //rename that to move it
}else {
   //file doesn't exist
}

[Unsupporting HTML in a Textbox]

What Michan said will work which will convert " to " and < to < etc...

 

If you just want to remove like bold, italic and other forms of HTML use strip_tags()

 

for your BBCode you would have to use a form of preg replace or str replace

 

for bold it would be something like

 

$find = "/\[b\](.*?)\[\/b\]/is";
$replace = "<b>$1</b>";

$bold_test = "hello my name is [b]marcus[/b]";
echo preg_replace($find, $replace, $bold_test);

[Help with a form]

You can have them act as image submit buttons.

[Failing to rename/move image]

Have you tried using the full path?

 

rename("/home/you/public_html/temp/".$_POST['user']."/file.jpg", "/home/you/public_html/gallery/".$year."/".$month."/".$day."/'.$_POST['user']."-"time()."_m.jpg");

[how do i write a nested loop to make a grid]

that's a lot of usage of the modulus.

 

<?php

echo "<table border=\"1\" cellspacing=\"3\" cellpadding=\"3\">";

$array = array("once", "there", "was", "a", "puppy", "who", "loved", "friendly", "people");


echo "<tr>\n";

$z = round(count($array)/3);

$x=1;
$y=1;
for($i=0;$i<count($array);$i++){
echo "<td>".$array[$i]."</td>\n";

if($x == 3){
	echo "</tr>\n";

	if($y != $z){
		echo "<tr>\n";
	}

	$x=0;
	$y++;
}

$x++;
}


echo "</table>";

?>

 

i'd say something like that is a bit simpler

[How can I make this code a link?]

I think you want to echo:

 

$row['id']

//not
$id

 

by the way if you don't want random searches don't include the allowment of "_" being searched

[MySQL Syntax Error]

Then login isn't defined, just replace $login with login in your query

[Referring page?]

if($_SERVER['HTTP_REFERRER'] == "/start.php"){
echo "HELLO";
}

[MySQL Syntax Error]

Sure, try echoing $login and see if it really is defined.

[database not accepting values]

Can you confirm the values you are trying to process to the database coincide with the database indefinite value?

 

INT, VARCHAR, TEXT, etc..

[MySQL Syntax Error]

No, it means there's no value within the two quotes.

 

Therefore, login isn't defined.

[Help with sending emails]

$subjbect = $_POST['subject'];

 

$body = "<h1>Hello, {$row[username]}</h1><br /><br />";
$body .="<p>".$_POST['message']."</p>";

 

$to = $row['email'];

 

mail($to, $subject, $body, $headers) or die("Failed to send e-mail");

[database not accepting values]

What's the error you have?

 

Try selecting the database before executing a query, and for queries check for errors

 

$result = mysql_query($query) or die(mysql_error());

[How can I make this code a link?]

$id isn't defined...

[MySQL Syntax Error]

Does the table even exist.

[MySQL Syntax Error]

You're changing the wrong query, silly.

[MySQL Syntax Error]

echo $query;

 

Try doing something like:

 

$query = "SELECT * FROM `". $login . "`";
