PHP - Simple Array Trouble

I'm just trying to incorporate some of what I've learned into practice and I can't believe I'm having problems with this but I really want to figure it out.

I'm trying to create a simple program where a user enters the name of a song, and gives it a rating (out of 5), and it displays the output first by song rating then (if the ratings are the same) displays it by the name of the song alphabetically. The idea in practice would work like this...user enters:

Quote

Song Name: My Song
Rating: 3

Song Name: His Song
Rating: 5

Song Name: Her Song
Rating: 5

Your list so far is:

Her Song - 5 stars
His Song - 5 stars
My Song - 3 stars



I just keep undoing things and clearly I'm not getting it. I had many ideas making it so I'll show you what I wrote (which isn't much): http://pastebin.com/2AGqgxQd

It looks terrible I know, I was just trying to find out how to put things from the form INTO an array and trying to output the array as I described above. If I could figure out how to use these session arrays to hold the entries from the post, then I'd be able to sort them properly, I'm just lost right now because everything I've read online and tried wasn't fixing the problem.

Thank you so much for the help!

I'm trying to modify my existing comment form to only allow users to post comments.  Right now anyone can visit the site and comment.

Here is my code

if($_POST['submit']){
if($_POST['$_SESSION['username']))==''){
$err = "You must login first";
}elseif($_POST['thecomment']==''){
$err = "You have to enter a comment.";
}else{
$username = strip_tags($_POST['username']);
$themessage = strip_tags($_POST['thecomment']);
$ezdb->get_results("INSERT INTO user_comments (id,date_added, posted_by, message, image_id) VALUE ('','".time()."','".$name."','".$themessage."','".$imageid."')");
$err = "Thank you for your comment.";
}
}


When a user is logged in, I still get the "you must log in error"  Help please.

First time poster, and very amateur php coder.  I am trying to delete items that in a list using ajax.  I can't figure out what I am doing wrong.  Any help would be greatly appreciated!

 

Here is a snippet of my javascript...

    $('.delete-item').click(function() {
        var itemID = $(this).data('itemID');
        var clear = 1;
        $.ajax({
            url: 'includes/delete-item.php',
            method: 'POST',
            data: {
                itemid:itemID,
                clear:1
            },
            success: function(data) {
                $('.content').load('includes/lists.php')
            }
        })
    })

 

and here is the relevant php...

$item = $_POST['itemid'];
$clear = $_POST['clear'];
$clearSQL = "DELETE FROM `List_Items` WHERE `item_ID` = $item";
$cleared = mysqli_query($connect, $clearSQL);

(php is a weakness)     Here is the HTML portion for the form:     <form action="send_form_email.php" id="contacts-form" method="post">

I've never used array's because I've always found a way to do something without them. I have finally taught myself how array's work, but I cannot seem to add a key and value to an array without my code creating another array inside that one. I'm not sure what I'm doing wrong, but this is what I'm getting.

From what I understand, print_r is suppose to print out an array. This is what my print_r displays:

Array ( [knife] => 2000 ) Array ( [baseballbat] => 2000 [knife] => 2000 ) Array ( [colt] => 2000 [knife] => 2000 [baseballbat] => 2000 ) Array ( [deserteagle] => 2000 [baseballbat] => 2000 [knife] => 2000 [colt] => 2000 ) Array ( [ingram] => 2000 [colt] => 2000 [knife] => 2000 [baseballbat] => 2000 [deserteagle] => 2000 ) Array ( [deserteagle] => 2000 [ump40] => 2000 [baseballbat] => 2000 [knife] => 2000 [colt] => 2000 [ingram] => 2000 ) Array ( [colt] => 2000 [ingram] => 2000 [deserteagle] => 2000 [knife] => 2000 [baseballbat] => 2000 [ump40] => 2000 [grenades] => 958 ) Array ( [baseballbat] => 2000 [ump40] => 2000 [colt] => 2000 [knife] => 2000 [deserteagle] => 2000 [ingram] => 2000 [grenades] => 958 ) Array ( [deserteagle] => 2000 [ingram] => 2000 [baseballbat] => 2000 [knife] => 2000 [colt] => 2000 [ump40] => 2000 [grenades] => 958 ) Array ( [colt] => 2000 [ump40] => 2000 [deserteagle] => 2000 [knife] => 2000 [baseballbat] => 2000 [ingram] => 2000 [grenades] => 958 ) Array ( [baseballbat] => 2000 [ingram] => 2000 [colt] => 2000 [knife] => 2000 [deserteagle] => 2000 [ump40] => 2000 [grenades] => 958 ) Array ( [deserteagle] => 2000 [ump40] => 2000 [baseballbat] => 2000 [knife] => 2000 [colt] => 2000 [ingram] => 2000 [grenades] => 958 ) Array ( [colt] => 2000 [ingram] => 2000 [deserteagle] => 2000 [knife] => 2000 [baseballbat] => 2000 [ump40] => 2000 [grenades] => 958 ) Array ( [baseballbat] => 2000 [ump40] => 2000 [colt] => 2000 [knife] => 2000 [deserteagle] => 2000 [ingram] => 2000 [grenades] => 958 ) Array ( [deserteagle] => 2000 [ingram] => 2000 [baseballbat] => 2000 [knife] => 2000 [colt] => 2000 [ump40] => 2000 [grenades] => 958 ) Array ( [ump40] => 2000 [pepperspray] => 2000 [colt] => 2000 [knife] => 2000 [ingram] => 2000 [baseballbat] => 2000 [deserteagle] => 2000 [grenades] => 958 ) Array ( [baseballbat] => 2000 [deserteagle] => 2000 [flashbangs] => 2000 [ump40] => 2000 [ingram] => 2000 [pepperspray] => 2000 [colt] => 2000 [knife] => 2000 [grenades] => 958 ) Array ( [pepperspray] => 2000 [colt] => 2000 [knife] => 2000 [baseballbat] => 2000 [ingram] => 2000 [ump40] => 2000 [deserteagle] => 2000 [flashbangs] => 2000 [teargas] => 1800 [grenades] => 958 ) Array ( [pepperspray] => 2000 [deserteagle] => 2000 [flashbangs] => 2000 [ingram] => 2000 [ump40] => 2000 [baseballbat] => 2000 [colt] => 2000 [knife] => 2000 [tasergun] => 1800 [teargas] => 1800 [grenades] => 958 ) Array ( [pepperspray] => 2000 [colt] => 2000 [knife] => 2000 [ump40] => 2000 [baseballbat] => 2000 [ingram] => 2000 [deserteagle] => 2000 [flashbangs] => 2000 [teargas] => 1800 [tasergun] => 1800 [combathelmet] => 1600 [grenades] => 958 ) Array ( [ingram] => 2000 [pepperspray] => 2000 [flashbangs] => 2000 [baseballbat] => 2000 [deserteagle] => 2000 [ump40] => 2000 [colt] => 2000 [knife] => 2000 [tasergun] => 1800 [teargas] => 1800 [combathelmet] => 1600 [grenades] => 958 [kevlarvest] => 271 ) Array ( [ump40] => 2000 [ingram] => 2000 [knife] => 2000 [deserteagle] => 2000 [colt] => 2000 [baseballbat] => 2000 [pepperspray] => 2000 [flashbangs] => 2000 [teargas] => 1800 [tasergun] => 1800 [combathelmet] => 1600 [grenades] => 958 [kevlarvest] => 271 ) Array ( [baseballbat] => 2000 [ump40] => 2000 [flashbangs] => 2000 [colt] => 2000 [pepperspray] => 2000 [deserteagle] => 2000 [ingram] => 2000 [knife] => 2000 [tasergun] => 1800 [teargas] => 1800 [combathelmet] => 1600 [grenades] => 958 [kevlarvest] => 271 ) Array ( [deserteagle] => 2000 [baseballbat] => 2000 [knife] => 2000 [pepperspray] => 2000 [ingram] => 2000 [colt] => 2000 [ump40] => 2000 [flashbangs] => 2000 [teargas] => 1800 [tasergun] => 1800 [combathelmet] => 1600 [grenades] => 958 [kevlarvest] => 271 )

Notice how the first array has one key/value, the second has the same value as the first plus an additional value. The third array has the same values as the second array plus an additional value. I'm confused as to whether my array is correct, and that print_t is just showing me how the array has changed everytime the while loop went through, or there is an error in my code and my array is not correct. I want to get this cleared before I continue. Here is my code so far:

Code: [Select]

<?

$user = $_GET['user'];
$attacks = $_GET['attacks'];


$quser = mysql_query("SELECT * FROM user WHERE username = '$user'");
$nuser = mysql_num_rows($quser);

if ($nuser == 1) {

$ruser = mysql_fetch_array($quser);

$totalpower = $ruser[power] + $ruser[defense];
$sabpower = round ($totalpower * $sabdmg);

$ramount = mysql_fetch_array(mysql_query("SELECT * FROM user_items WHERE username = '$user'"));

$wa = array();

$qweps = mysql_query("SELECT * FROM weaponstore ORDER BY type ASC, price ASC");
while ($rweps = mysql_fetch_array($qweps)) {

$wepname = $rweps[colname];
$wepamount = $ramount[$wepname];

if ($wepamount >= 1) { $wa[$wepname] = $wepamount; }

arsort($wa);
print_r($wa);



}

}


?>


Basically the code should add the $wepname as the key and $wepamount as the value to an array $wa only if $wepamount is >= 1, but the way my print_r is showing it I'm just confused as to why I'm getting a bunch of arrays and not just one.
