PHP - Moved: Passing Array From Php To Javascript Using Html Button

http://www.phpfreaks.com/forums/index.php?topic=332103.0 Similar TutorialsI know this is 'old stuff', but I am new to this and very frustrated- I am trying to pass a variable to a new url via an html onclick event, and failing. I have found several posts about it but the code posted in those posts does not work when I try it. I have struggled mightly with this. Here is my code: first an echo of two versions of the onclick statement, and two versions of the actual button code. The echos from the two versions appear identical, but the first button with no variable works while the second using a variable results in no action. Can anyone point me in the direction of a solution? I suspect there is some simple principal I am missing relating to parsing strings. <?php echo "window.location.href='ManageTitles.php?dog=2'"; echo "\n" ; echo "window.location.href='ManageTitles.php?dog={$row_rsDogsowned['idDogInfo']}'"; ?> <form methd="POST" Name="form3" action="<?php echo $editFormAction; ?>"> <input type="button" value="works" onclick="window.location.href='ManageTitles.php?dog=2'" /> <input type=button onclick="window.location.href='ManageTitles.php?dog={$row_rsDogsowned['idDogInfo']}'" value="fails" /> </form This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=347628.0 This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=355358.0 Hello Everyone!

Code: [Select] echo "<tr>"; echo "<td name='".$cell1['value']."'>".$cell1['value']."</td><td name='".$cell2['value']."'><a href='file.php'>".$counter."</a><input type='button' name='buttonName' onclick='submit('.$cell1['value'].');'></td> <td name='".$cell2['value']."'><a href='file.php'>".$counter."</a><input type='button' name='buttonName' onclick='submit('.$cell1['value'].');'></td>"; echo "</tr>";When one of the buttons is clicked I want to pass cell1value to the processing script. Is this the correct way to do it? And how do I access $cell1['value'] after submission? Given the following array $documentlist, displayed from print_r Array ( [MerchantDocumentInfo] => Array ( => Array ( [documentID] => 2760322451 [generatedDateTime] => 2010-08-03T16:02:45-07:00 ) [1] => Array ( [documentID] => 2761837402 [generatedDateTime] => 2010-08-03T23:01:15-07:00 ) ) ) I'm trying to figure out the syntax to use the documentID as a dynamic variable When I 'hard code' the variable, I get the document I want eg $order = $t->GetDocument('2760322451'); -- returns requested document info into $order array where $order is an array and $t are my connection credentials. I've made numerous attempts, but get errors in anything I try. Can someone tell me the correct syntax to use to pass a dynamic value for documentID from the $documentlist array at the top? I've tried $order = $t->GetDocument($documentlist['MerchantDocumentInfo' ]['documentID']) ; and get ===> syntax error, unexpected '[', expecting ']' $order = $t->GetDocument($documentlist->MerchantDocumentInfo[0]['documentID']) ; get nothing $order = $t->GetDocument($documentlist->MerchantDocumentInfo[1]['documentID']) ; get nothing $order = $t->GetDocument($documentlist->MerchantDocumentInfo[1][documentID]) ; get nothing Thanks in advance for any ideas, I've been trying to figure this out for days. Hi there. I have this course registering website whereby i will need to : 1. pull out all course info and display (done that) 2. when user choose the course they are interested in using radio button and click submit , it will display you're registered and update the database to decrease the head count by 1. i m stuck on the radio button part... after i click submit nothing happens... Please advice... thanks a lot Code: [Select] <html> <head> <title>TimeTable</title> </head> <body> <h1> Here is the timetable</h1> <?php @ $db = new mysqli('localhost', 'root', '', 'mylifestyle'); if (mysqli_connect_errno()) { echo 'Error: Could not connect to database. Please try again later.'; exit; } $query = "SELECT course.CourseName , course.Instructor , course.ClassSize , courseschedule.Date ,courseschedule.Time , courseschedule.Location FROM course INNER JOIN courseschedule ON course.CourseID = courseschedule.CourseID"; $result = $db->query($query); $num_results = $result->num_rows; echo "<table border='1'> <tr> <th>Course Name</th> <th>Instructor</th> <th>Class size</th> <th>Date</th> <th>Time</th> <th>Location</th> <th>Register</th> </tr>"; ?> <?php for ($i=0; $i <$num_results; $i++) { $row = $result->fetch_assoc();?> <tr> <form action = "" method = "post"> <td><? echo $row['CourseName']; ?></td> <td><? echo $row['Instructor']; ?></td> <td><? echo $row['ClassSize']; ?></td> <td><? echo $row['Date']; ?></td> <td><? echo $row['Time']; ?></td> <td><? echo $row['Location']; ?></td> <td align="center"><input name="radio" type="radio" id="radio[]" value="<? echo $row['ClassSize']; ?>"></td> </tr> <?php } ?> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="submit" type="submit" id="submit" value="submit"></td> <?php if($submit){ for($i=0;$i<$num_results;$i++){ $del_id = $radio[$i]; $query = "UPDATE course SET ClassSize = ClassSize -1 Where id='$del_id'"; $result = mysql_query($query); } // if successful redirect to delete_multiple.php if($result){ echo "$CourseName was deleted from database - myliftstyle!!<br />"; // Compute the item costs and total cost } } ?> </div> </body> </html> [attachment deleted by admin] I have some function or method. Is there a better design patter to implement this?
function myFunction($a=null,$b=null,$c=null,$d=null,$e=null,$f=null,$g=null,$h=null)
{
//Do a bunch of stuff
}
Maybe the second function?
function myNewFunction($data=array())
{
$data=array_merge(array('a'=>null,'b'=>null,'c'=>null,'d'=>null,'e'=>null,'f'=>null,'g'=>null,'h'=>null),$array);
//Do a bunch of stuff
}
Please provide decision making factors why you would use one approach over the other.
$seat_s is a $var that can have multiple values depending on a form in a previous page. this code works fine as is, but i need to pass the array into a 3rd page. i have no idea how to do this from the code below. ive tried passing the array straight into a _post then _get on the next page but that only holds the 1st value and not all of them. suggestions please.... thanks <?php $seat_s = $_POST['seats']; foreach($_POST['seats'] AS $seat) { $rowId = substr($seat, 0, 1); $columnId = substr($seat, 1); echo $rowId . $columnId . ", "; } ?> Hi all, new to php and struggling passing an array via url. first page: Code: [Select] $str = serialize($cartinfo); $strenc = urlencode($str); <A href="/test/getcart.php?cartinfo=<?PHP echo $strenc; ?>">test</A> Which does add a long string to the URL so I guess to here it's fine. Second Page: Code: [Select] <?PHP $cartinfo = unserialize($_GET["cartinfo"]); var_dump($cartinfo); ?> However all I get is: bool(false) Any advice would be great, I also tried adding $cartinfo to the session, but this didn't work either. Surely passing variables should be straight forward??? Thanks.

But I can't do anything with the classes, because it's some how made an array of an array??? I wrote: $wid = $_POST['wid']; print_r($wid); This produces--- Array ( => Array ) I want it to give me the original array? Is there a different way to do this? I recently posted a simple query about ISSET and finally got that simple problem solved thanks to you guys. But I've hit a new snag. I've create a simple sort of cart, or record counter. While I can add/remove/clear items and display their affilated arrays, I don't know how to cycle through a multidimensional array that is dynamically set.
Something like $_SESSION['Primary'][$items][$attributes] - Where $items is a dynamic set, and $attributes is a fixed set of keys with values.
I can target individual $Items, or display all the items in there. But I can't display all the Items and their subsequent $attributes aswell. Do I have to write 1 set of Ajax code for just displaying the $items, and another for each individual set of $attributes? Or is their a way to cycle through each $item, and then all of it's(or specific) $attributes and values? I've tried using loops which logically work, but I can't pass it through json_encode.
Is there any documentation I could read in relation to this? I feel this is the key component to manuvering through a database of sorts. I'm just not entirely sure how to go about accessing multidimensional Array's without a ton of code that becomes redudent. And even then, it wouldnt work well with a dynamic setup.
