PHP - Php Endless Problems Please Help!!

First
Since I first started learning PHP, I've been writing code for forms like this:

$name = $_POST["name"];

if ($name == "") {
echo "You didn't type anything";
}

I've written scripts like this and tested them on a GOdaddy server, and they always worked fine.

Now, after testing scripts like that on my own server (WAMP2 [PHP5, Mysql, Apache]), I get an error saying "Unidentified index: name", and so I have to nest that if statement AS WELL AS the variable assignment inside another if statement like this:

if (isset ($_POST["name"])) {
$name = $_POST["name"];
if ($name == "") {
echo "you didn't type anything.
}
}

The error doesn't actually stop the script from running, but a medium sized box appears in the browser with the error message contained that's after the element in the document of which is getting an invalid error.

Which way is truly the correct way? Because now that I have to use the second way in order for my scripts to run correctly on my own server, I have to write more code and it all gets disorganized and more complicated to read.

So...is this a configuration thing that I can tweak in WAMP2 to stop messages like that from popping up? Or is the second way the way you're supposed to do it?

Also, I was wondering why ereg got deprecated and what the replacement of it is in PHP5? I've asked before and even googled it but I simply get taken to a "Pearl" function on PHP.net. I'm not sure what it is, or how to use it, and haven't got any hints from either PHP.net or anywhere else.

Any suggestions?

Hi, I hope someone can help me.  I am trying to generate a script for our Intranet that tells me which birthdays = today.  My field in my table = d/m/y, eg 09/05/2011 (9 May 2011).  How do I get the script to just look at the day & month, not the year?  My script looks like this:

Code: [Select]
<?php

echo date("d/m/Y") . "<br />";
$myDate = date('d/m/Y');
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("dbname", $con);

$sql = "SELECT * FROM detail WHERE dob='$mydate'";
$result=mysql_query($sql);
echo mysql_num_rows($result);

?>

Hello,

Alright I am having a few issues here. Let me explain what I am doing...this is a script that allows a customer to split an order..he can split certain items out of one order and it will create another order with the items he split added to this order, and then subtracting the items from the old order. The products are stored in one field called products, they are stored in a delimited list like this qty, product name, price each, product id | qty, product name, price each, product id |etc.

Now, before you say why are you storing your products like that?? The reason I have to store my products like so is because the customer does not want the products stored in the order table to be dependent off the products table like they were before. In that case if he modified a product it would modify all of the orders with that product stored in them. Make sense? I am aware a delimited list probably wasn't the best way to do this but it was the best way I could think of.

Ok here is my list of issues.
  1) Everytime you split an order, it is not creating a new order to store the items that were split into. It created an order the first time I did it, and now all it does is it keeps updating the products field in that order, rather than creating a new order.
  2) Next I do not know how I can update the old products (stored in the $prod array). It needs to update the products qtys after the order was split, and then if all of the qty for that product were moved to the new order it just needs to remove that product from the $prod array rather than updating the quantity.

The code is below. Please let me know if I can provide any more information to help! Thanks everyone!

Hello,
I'm having trouble with zip_read.  I made a zip of 2 plain 8k text files and zipped them w/ winrar using default settings.  I opened the file w/ zip_open and then checked to make sure the return value was a valid resource, which it is.  But when I try to use the return value of zip_read I get:
Quote

Warning: zip_entry_name() expects parameter 1 to be resource, boolean given in xxx

It is actually returning "1".  According to the zip error codes I think this means "Multi-disk zip archives not supported".  I have no idea what a 'multi-disk' zip file is.  I've posted my code below. 

How can I get php to read through a zip file?

Thanks

Code: [Select]
       
        $zip = zip_open($this->upload_path . $filename);
        if (is_resource($zip)) {
          $i = 0;
          while($zip_entry = zip_read($zip) && $i<500 ){
          if($this->debug) echo "zip_entry=" . $zip_entry . "<br>";
          $basename = basename(zip_entry_name($zip_entry));
          $zipped_file = $this->upload_path . $basename;
                // other unrelated code
          }
        }

I am trying my hand at using an array i have never done it before, and I am having some problems getting it work work. if someone could point me in the right direction?

Thanks



<?php

$active_keys = array();
foreach($_GET['img'] as $key => $filename)
{
    if(!empty($filename))
    {
        $active_keys[] = $key;
    }
}

Hi... I have a string (called $textData) with the following format:
Code: [Select]
1. e4 {[%emt 0:00:10]} c5 {[%emt 0:00:04]} 2. c3 {[%emt 0:02:15]}etc

I need to replace the square brackets/special chars within that string with " "...  so my first thought was to use preg_match to find the matches.. then preg_replace/str_replace to update them.

To find the patterns, I think this is correct:
preg_match('/\{([^\}]*)\}/', $textData, $matches);
echo print_r($matches, true);
// returns Array ( 
[0] => {[%emt 0:00:10]} 
[1] => [%emt 0:00:10]
 ) 
// returns nothing else

I expected the preg_match to search through the whole of $textData.  Then I could replace the square brackets/special chars with a spaces. 

Thank you for your time!!

Hello there, well basically what this function does is look at all the entry's to find a unused port in the database but when I run the function the first time if the table is empty mysql_insert_id works fine, but then if I run it again the mysql_insert_id keeps returning 0, I am using it immediately after the query but its not working properly, can anybody shed some ideas into the matter, anything is appreciated!, thanks for your time!:

I am trying to retrieve an attribute from a node and I keep getting the error:

Any ideas on what I may be doing wrong?

This script works fine except, the a href only displays baseurl/current_folder instead of baseurl/other_folder/other_folder/current_folder

I'm sure it's simple, but I can't figure it out.

Code: [Select]
function breadcrumbs($separator = '', $home = 'Home') {

    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
    $base_url = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
    $breadcrumbs = array("<p><a href=\"$base_url\">$home</a></p>");

    $last = end(array_keys($path));

    foreach ($path AS $x => $crumb) {
        $title = ucwords(str_replace(array('.php', '_'), Array('', ' '), $crumb));
        $title = ucwords(str_replace(array('.html', '_'), Array('', ' '), $crumb));
        if ($x != $last){
            $breadcrumbs[] = "<p><a href=\"$base_url$crumb\">$title</a></p>";
        }else{
            $breadcrumbs[] = "<p>$title</p>";
}
    }

    return implode($separator, $breadcrumbs);
}

echo breadcrumbs();

I have a config file that lists a file like so..

Code: [Select]
$file1 = 'storagefolder/mydatabase.txt';
How can I delete the file "mydatabase.txt" that is in another directory 'storagefolder' ?

Code: [Select]
unlink($file1);gives an error that says not such file or directory
