trying to pass the array of $_POST form variables through a function

hi,
i'm trying to get the variable $attribs to contain the array of attribute descriptions and values from the database, but i keep getting the following error passed through ajax.

Warning: Invalid argument supplied for foreach() in C:\XAMPP\htdocs\fab\scripts\request_handler.php on line 32

the post string sent to the request_handler.php page is the following:

Code:

"menu_services=1&text_consumerfullname=Piet%20Pompies&text_consumeremail=pierre%40greywacke.co.za&attribute=1&attribute=2&menu_regions=8&text_leadsubject=test%20subject&text_leadmessage=test%20message"

the function that is defined there is the following, followed by the call:

PHP Code:


			
function getattribs($arr) {
    $arr2 = array();
    foreach ($arr as $key => $val) {
        $sql = "SELECT bigint_AttributeID, text_AttributeDescription, text_AttributeValue
 FROM 3_serviceattributes WHERE bigint_AttributeID = ".$val.";\n";
        $GLOBALS["sql"] .= $sql;
        $result = mysql_query($sql);
        $err = mysql_error();
        $GLOBALS["sql"] .= strtoupper($err)."\n";
        while ($row = mysql_fetch_array($result)) {
            array_push($GLOBALS["attribids"],$arr2,$row["text_AttributeID"]);
            array_push($arr2,$row["text_AttributeDescription"]." = ".
$row["text_AttributeValue"]);
        }
    }
    return join("<BR>\n",$arr2);
}
$attribs = getattribs($_POST["attribute"]);

i've tried passing the array as attribute[] too, but that did not work too well. how should i use the for loop in this case? i'm not sure it's being passed correctly?

i've added the array() method around the $_POST["attribute"] request to ensure it's an array. that solved the error, but now it doesn't step through the first $key = attribute $val = 1... only the second which is 2... i see this because the processed queries added to $GLOBALS["sql"], only includes the query for value 2 - there should be one for value 1 as well, here is the processed queries (if an error occurred, the following line contains it):

Code:

SELECT bigint_AttributeID, text_AttributeDescription, text_AttributeValue
FROM 3_serviceattributes WHERE bigint_AttributeID = 2;

not sure i'm doing that correctly, how can i process this that ALL attributes passed are stepped through, wether one or more?

also noticed the extra parameter in the first array_push() method.

apparently not yet. how can i get the joined array to be by a <br /> tag followed a new line? for some reason it's not parsing the string as regexp.

PHP Code:


			
return join("<br />\n",$arr2);

okay, i guess this issue is resolved now, not putting the attributes on their own lines. the \n was removed. it would still be helpful to know how to insert a new line as a seperator with join functions in php though... i guess one could always do it by character code.

Hi, I am new to php. I am using a Macintosh OSX 10.7.5 and XAMPP. I have been following a series of tutorials on youtube and in one of them method = 'POST' this is used in a html document. The corresponding php document uses :
$number = $_POST['number'];

then $number is used in a conditional as follows:
if($number < 50) {...
it doesn't matter if the number submitted on the html document side is greater than or less than 50 the conditional evaluates to true in both cases. If I substitute on the html side method = 'GET' and use on the php side $number = $_GET['number']; the conditional evaluates correctly

echo "<?php phpinfo(); ?>" >> blah.php informed me that php 5.3.1 was operatijng

I had also MAMP and I tested operation under that framework to find the system operated identically.

does any1 have a clue as to why this is operating so?
