Condintional statements when posting a form
Posted: Wed Dec 09, 2009 12:34 am
Hi Guys
I have an upload form as displayed below
and am looking to add a conditional statement that says if the user selects 'No' from the 'make this my default picture' area of the form then post
However, if the user selects 'Yes' I want the form to post
The problem is I'm not entirely sure how to write the code, I've looked into if..else statements and have tried to specify what Ive explained in this forum but am going wrong somewhere, would really appreciate help on this one
I have an upload form as displayed below
Code: Select all
<?php
include('design/header.php');
require('connect.php');
$id = $_SESSION['id'];
//This function separates the extension from the rest of the file name and returns it
function findexts ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-1;
$exts = $exts[$n];
return $exts;
}
//This applies the function to our file
$ext = findexts ($_FILES['uploaded']['name']) ;
//This line assigns a random number to a variable. You could also use a timestamp here if you prefer.
function str_rand($length = 8, $seeds = 'alphanum')
{
// Possible seeds
$seedings['alpha'] = 'abcdefghijklmnopqrstuvwqyz';
$seedings['numeric'] = '0123456789';
$seedings['alphanum'] = 'abcdefghijklmnopqrstuvwqyz0123456789';
$seedings['hexidec'] = '0123456789abcdef';
// Choose seed
if (isset($seedings[$seeds]))
{
$seeds = $seedings[$seeds];
}
// Seed generator
list($usec, $sec) = explode(' ', microtime());
$seed = (float) $sec + ((float) $usec * 100000);
mt_srand($seed);
// Generate
$str = '';
$seeds_count = strlen($seeds);
for ($i = 0; $length > $i; $i++)
{
$str .= $seeds{mt_rand(0, $seeds_count - 1)};
}
return $str;
}
//This takes the random number (or timestamp) you generated and adds a . on the end, so it is ready of the file extension to be appended.
$ran2 = str_rand(12, 'ABCDEFGHJKLMNPQRSTUVWXYZ0123456789').".";
//This assigns the subdirectory you want to save into... make sure it exists!
$target = "store/";
//This combines the directory, the random file name, and the extension
$target = $target . $ran2.$ext;
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
$sql = "INSERT INTO `users`
(`userid`,`location`)
VALUES ('".$id."','".$ran2.$ext."')";
$res = mysql_query($sql) or die(mysql_error());
echo "The file has been uploaded as ".$ran2.$ext;
}
else
{
echo "<br /><font size='6' face='arial' color='#33cc00'>Picture Upload</font>";
}
?>
