PHP - Getting Javascript Array To Php
Hi.
I'm pretty new to php and javascript. Perhaps I'm going about this all wrong, so any ideas will be appreciated... I've got a php-generated form that calls an external javascript function (through onclick of button input) to validate an array of checkboxes. If the user presses ok on the javascript confirm box, it does a submit of the form. The checkboxes are a javascript, rather than php array: echo "<input type=\"checkbox\" name=\"attuids\" value=\"$dirReportUid\" class=\"CheckField\">$dirReportUid<br>\n"; What I need to do is get the array of checked boxes from my javascript array into a php array in the php script called by the submit action. Here's the javascript: Code: [Select] function CheckboxTest(list) { total = ""; outArray = new Array(); outCount = 0; for (i=0; i < list.length; i++) { if (list[i].checked) { total += list[i].value + "\n"; } } if (total == "") { alert("No direct reports have been selected"); } else { alertMessage = "You have selected the following users\n"; alertMessage = alertMessage + "for Patrol Console deletion:\n\n"; alertMessage = alertMessage + total + "\n"; if (confirm(alertMessage)) { document.myForm.submit(); } } } Here's the php: Code: [Select] <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Patrol Console Audit</title> <link href="css/ConsoleAudit.css" rel="stylesheet" type="text/css"> <script type="text/javascript" src="javascripts/CheckboxProcess.js"></script> </head> <body> <h2>Patrol Console Audit</h2> <?php $patrolConsoleFile = "/home/rfg/ATT/console.userlist.csv"; $directReports = array(); $PATROLFILE = fopen("$patrolConsoleFile", "r"); $checkUid = "cr6228"; while (!feof($PATROLFILE)) { $fileLine = fgets($PATROLFILE); $patrolUserData = trim($fileLine); if (empty($patrolUserData)) { continue; } list ( $mgrData, $mgrDirReportUid, $mgrDirReportName, ) = explode(',', $patrolUserData); list ( $mgrName, $mgrUid, $mgrEmail, ) = explode(':', $mgrData); if ($mgrUid == $checkUid) { array_push($directReports, "$mgrDirReportUid $mgrDirReportName"); } } $firstName = "Jerry"; $lastName = "Garcia"; if (count($directReports) > 0) { echo "<h3> Direct Reports for $firstName $lastName</h3>\n"; echo '<form action="ProcessConsoleAudit.php" method="post" name="myForm">'."\n"; echo '<input name="checkedBoxes" type="hidden", id="checkedBoxes" value=""/>'; echo '<h4>Select users to retain Patrol Console access</h4>'."\n"; echo "<fieldset class=\"InputFields\">\n"; echo "<br><input type=\"checkbox\" name=\"CheckAll\" class=\"CheckField\" onclick=\"CheckUncheckAll(document.myForm.CheckAll,document.myForm.uids)\">Check All</br>\n"; echo "<br></br>"; foreach ($directReports as $dirReportUid) { echo "<input type=\"checkbox\" name=\"uids\" value=\"$dirReportUid\" class=\"CheckField\">$dirReportUid<br>\n"; } echo "</fieldset>\n"; echo "<div class=\"SubmitDiv\">\n"; echo '<input type="button" value="submit" class="SubmitButton" onclick="CheckboxTest(document.myForm.uids)">'."\n"; echo "</div>\n"; echo "</form>\n"; } else { echo "<br> No direct reports were selected<br>"; } ?> </body> </html> Thanks very much for any comments and/or ideas, Rick Similar TutorialsI need a help in the following : I have an admin page from where the admin attaches an gif image.This attached image should be shown to the user as a scrolling image. The code for the scrolling image is done through javascript. So my actual problem is getting the name of the attached gif image to the javascript array which is used for scrolling horizontally. Hello Everyone! I have created a javascript array which now i want to pass to php, so php can store those values to mysql. So please anyone can suggest me how do i pass it to php? Any help will highly be appreciated! I initially set up a few VAR items to learn some JS coding.
Then it became apparent that altering the group and entering them into an array would be more effective.
However, my limited knowledge is confusing the situation.
Is there a simple comparison (with proper code and formatting) that someone can provide?
Example: student in the school
info desired: name, age, hair color, eye color
As separate VAR listings I cannot sort by age, so I create an array, but how can I name them student 1, 2, 3 etc. (or do I not want to??).
As part of a form submission, I have several textboxes The textboxes have an array name such as text[]. I'm sending the textbox values via http request. Sending an element value via http request is usually be done using document.getElementById, assigning the elements ID to a var and posting the var name . Then accessing the value using $_POST. However I'm sending an array of string values. How do I access the array using $_POST? Any help appreciated. Hello everyone I need your assitance a great deal, so I have a form which i submitted to a php file throug ajax and jquery. It is working A ok but I want to be able to submit it with javascript instead, so i don't load any lib. And it is now a problem. The method I use to get the form field names and values in jquery is so simple and dynamic hence if changes are made on the html form i don't have to edit my jquery file to effect the change ie in respect to changing the name of the fields or adding more fields. But I don't know to archieve this using javascript. So i want to post my jquery script, for you all my mighty programmers to assist me get a javascript Clone for me, thank you very much for Helping Jquery file $("form.ajax").on("submit", function(){ var that= $(this); that.find('[name]').each(function(index,value){ var that = $(this), name =that.attr('name'), value =that.val(); data[name]=value; }); return false;}); Now the above code is just my major focus of the script. What it does is that select the form with an ajax class attribute and run a function after the user submits the form. The var that get reference to the above form throug the (this) reference. Next i use find fuction to look through out the open and close of our form.ajax form for any element that has the name attribute and set it into array using the .each(function (index,value){}) this is my main focus how to ilterate through the form looking for name attribute and set my finding into array using javascript. The next that var reference to the find statement and then we steal the name attribute and value from our findings and set an array called data with the stolen name variable as its index n value attribute as its value. Thank you once more my aim again is with the find and array setting statement. Hello =) I'm trying to create a javascript array which should be filled with data from a mysql database. so what i wannt to do is to loop out a new array element for each row in my database. I should also say that i'm working in a php file. I tried (and failed) to do it like this: Code: [Select] <?php include('databbaseconnect.php'); ?> <script type="text/javascript"> var StoreDetails = [ ['Please select an option','','','','',''], <?php mysql_select_db("alltomboule_se", $db); $result = mysql_query("SELECT * FROM spelare"); while($row = mysql_fetch_array($result)) { echo "['".$row['namn'].$row['enamn']."','".$row['namn'].",'".$row['enamn']."','".$row['klubb']."','".$row['licensnr']."','".$row['id']."'],"; } ?> ['','','','','',''] // Note: no comma for last row ]; I wannt the array to look like this: Code: [Select] var StoreDetails = [ ['Please select an option','','','','',''], ['Oscar Andersson','Oscar','Andersson','BON','16643','2'], ['Olle Johansson','Olle','Johansson','BFT','14443','3'], ['Ingvar Andersson','Ingvar','Andersson','BON','14333','4'], ['Kalle Kula','Kalle','Kula','BON','34576','5'], ['','','','','',''] ]; This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=332103.0 NOTE - Please read the information first as it contains important information to understand the problem.

Thanks.. I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription. I am trying to pull the shortdescription from the listings table with the query $shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' "))); The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462 The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them. Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data? So I'm trying to create an Array from a comma separated string containing array{s}. How can I take a string full of comma separated hex values such as : <?php $myStr = ( "00ffff", "00cccc", "009999", "007777", "004444", "001111", "01ffff", "01cccc", "019999" ); ?> & turn it into 3 separated arrays like : <?php $myNewArrs = [ Array1 ( 3 ), Array2 ( 3 ), Array3 ( 3 ), ]; ?> which REALLY looks like :
<?php
$myNewArrs = [
Array ( "00ffff", "00cccc", "009999" ),
Array ( "007777", "004444", "001111" ),
Array ( "01ffff", "01cccc", "019999" ),
];
?>
? Thank you & have a great afternoon!
Edited May 27 by AquariaXI Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=344127.0 Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. I have mysql select query shown below retrieving data from a database:
$sql = "
SELECT
student, sum( test_score ) as score
FROM
test
INNER JOIN
level
ON
test.level_id = level.level_id
GROUP BY
student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
while ($row = $result->fetch_array(MYSQLI_ASSOC))
{
var_dump($row);
}
}
On inspection of the retrieved array with var_dump(), i have these result below:
array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. I have a associative array and I need to compare it to a normal array. Code: [Select] associative will have anywhere from 2-8 of these ['name'] ['color'] ['uid'] Code: [Select] normal array will have anywhere from 1-8 names ['name'] What I need to do is get the name of the people that are in the associative array that are not in the normal array. I've tried all sorts of different loops and what not and I cant seam to get anything to work in every case. Hi, I am very new to PHP and apologies if this question has already been answered in another thread.
I am trying to extract the information from one array into another when some search criteria is matched.
Here is an example array ($original):
Array ( [ 1234567 ] => Array ( [name] => john ) [ 3456 ] => Array ( [name] => johnny ) [ 45673 ] => Array ( [name] => james ) [ 987 ] => Array ( [name] => jamie ) [ 5628721 ] => Array ( [name] => Simon ))
So if I searched for the string john, jo, joh then the new array ($filtered) should be as follows:
Array ( [ 1234567 ] => Array ( [name] => john ) [ 3456 ] => Array ( [name] => johnny ))
I was trying to do this using array_search & preg_match but have been struggling.
Any help would be much appreciated!
I need to some how pull comma separated images $data[23] from this $data array and then put them into there own array so I can insert them into separate rows in a database. This is the provided array: $data[0] => VIN $data[1] => StockNumber ...(all the other number here) $data[23] => Image_URLs (comma seperated) $data[24] => Equipment // I need something like this (obviously doesn't work?!@#) $delimiter = ","; $img = explode($delimiter, $data[23]); foreach($img as $pic){ $sqlPic = "insert into class_prodimages (pid image rank) values('".$LastId['id']."', '$pic', '".rand(1,20)."')"; } Any help here? |
