PHP - Dynamic Array Multisort
Hi,
Is there any way to pass dynamic arguments to array_multisort. Below is my idea of what the code should look like. First it has the data then its builds an array of array indexes with the sort direction. This array is then passed to the array_multisort function with the original data. Code: [Select] $data[] = array([0] => 67, [1] => 2, [3]' => 2001); $data[] = array([0] => 86, [1] => 4, [3]' => 2002); $data[] = array([0] => 98, [1] => 5, [3]' => 2002); $data[] = array([0] => 86, [1] => 6, [3]' => 2003); $data[] = array([0] => 67, [1] => 1, [3]' => 2004); $arg = array(1 => SORT_ASC, 3 => SORT_DESC); array_multisort($arg, $data); I have got this working with hardcoded values, for example... Code: [Select] array_multisort($sort1, SORT_ASC, $sort3, SORT_DESC, $data); but in my code instead of just 2 sorts there could be 'x' amounts. I hope ive made this clear. Any response would be much appreciated. Thanks in advance. Similar TutorialsHello 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. I'm scraping a housing website with html source: Code: [Select] <tr><td> </td><td> Bedrooms </td><td> </td><td >3</td><td> </td></tr> <tr><td> </td><td> Full Baths </td><td> </td><td >1</td><td> </td></tr> <tr><td> </td><td> Partial Baths </td><td> </td><td >1</td><td> </td></tr> <tr><td> </td><td> Interior Sq Ft </td><td> </td><td >1,356</td><td> </td></tr> <tr><td> </td><td> Acres </td><td> </td><td >0.16</td><td> </td></tr> What i'm trying to do is create an associative array with only the details I want from the above. I've already got a function that steps through the HTML and creates an array element for each row with the contents of each <td> statement as follows: Code: [Select] $repl = array(" ", "(", ")"); $repl_with = array("", "", ""); foreach ($rows_feat as $id2 => $row2){ $features_raw = $scrape->fetchAllBetween('<td','</td>',$row2,true); //$features_data[str_replace($repl,$repl_with,strtolower(trim($features_raw[1])))] = trim($features_raw[3]); $countid=$countid+1; } The array produced by this would look like: features_raw[1] = Bedrooms features_raw[3] = 1 Basically, I want to take data like this: Beds 1 Baths 1 Garage Yes and create an array on the fly: House[beds]=1 House[baths]=1 House[garage]="yes" The problem is that the order of Beds, Baths and Garage changes. So on some house pages the order would be Baths, Garage, Beds.. etc. Any pointers out there? Thanks, Brett How can I use php to update a dynamic amount of input fields and tell mysql which ones to update respectively? Essentially I have a list of occupations and if someone wants to update one of them I don't know how to tell php which one they've changed in a dynamic way. Code: [Select] <?php if(!empty($occupations)) { ?> <h3 id="job_function">Job Functions</h3> <?php $i = 0; foreach($occupations as $occupation) { ?> <div class="formElement"> <div class="formFieldLabel "> <label for="occupation_<?php echo $i; ?>"><?php echo $occupation['companyname']; ?></label> </div> <div class="formField"> <input id="occupation_<?php echo $i; ?>" type="text" name="occupation_<?php echo $i; ?>" value="<?php echo $occupation['function']; ?>" /> </div> </div> <?php $i++; } } ?> Hi ! I'd like to count all occurences in "$thiscodestring" into a "dynamic?" array and print it out after the end of the loop, how do I assign the variablenames dynamically ? $query = "SELECT codes, status FROM table"; while ($row = mysql_fetch_assoc($result)) { $thiscodestring = $row[codes]; // looks like "a1 c2 d3 10 15 1 a1 a1"; $singlecodes = explode(" ", $thiscodestring); foreach($singlecodes as $thiscode) { $$thiscode[count] = $$thiscode[count] + 1; } } After all Mysql-Stuff is done I'd like to print out the counted codes, for example the code "a1" was found 100 times in all querys then $$a1[count] should be 100, c2 was found 15 times, then $$c2[count] should be 15 and so on. Question: How do I tell php to assign a "dynamic" variable with the name of the found string which was exploded (in this example a1, c2, d3... ) before ?! $$ does not seem to work. And how can I then print_r() the value if I dont know the name ? Thanks ! Hi all. I am currently trying to build a site that will allow users to manage a self build house project. This is my first php MySQL project but I am getting to grips with it ok. I am currently building this for my own benefit at the moment as I am about to undertake a self build. I have a few questions to put to you guys. This is where I am at the moment I have a database table named materials which contains a list of materials , quantities, unit of measurement, id. My site has a user control panel that has separate forms for each stage of the build where the user enters the quantities of the materials, and the data is displayed as an array for each stage. So, heres question 1. I want to take the data and use it to generate a form which will be completed by several merchants.... so it will display similar to the array but will be a form with a text box for price where the merchant will insert a price. i.e <?php mysql_connect ("localhost", "test", "test") or die ('I cannot connect to the database becuase: ' . mysql_error()); mysql_select_db ("matquant"); // query $query = mysql_query("SELECT * FROM `quantites` ORDER BY `id` ASC"); // results while ($row = mysql_fetch_array($query)) { echo "<br />" .$row ['id']. " " .$row ['material']. " " .$row['quantity']. " " .$row['unit']. "<br />";} echo mysql_error(); ?> I want to add a text input box form which will allow the merchant to add a price to each item that is added to the array. so there the merchant will be able to give me a price for all the items in my list. Heres where I get stuck.... as I am constantly adding to the list I have no fixed amount of items so the form for the merchants needs to be built dynamically, ie each time I add a new material, I want the merchants form to get a new input. I am not very good at describing my problems but I am hoping that someone can help me out from the information given. Thats the first question. i like to get issues sorted in small bites. the second is the next big bite, I want to send the form above to several merchants, so I intend to have a user database with a user for each merchant, and link the tables so that each merchant can provide a price for each material, ideally the form would highlight the materials that have not had a price yet. I'm looking for advice on the best method of doing this basically but if I can get the first question sorted that would be great.. I have the test site local but can upload it it to the server if it will help you see what im trying to do. Any help that anyone can give will be greatly appreciated. In brief, I'm attempting to capture the form data from a dynamic form to a mysql database. From he

It has been suggested that I explore using the PHP Explode() function. It's possible that may work, but can't get my head around how to apply the function to the PETLIST Array. Looking for suggestions or direction to find a solution for this challenge. Looking forward to any replies. Folks, I need help (Php code ) to generate a Dynamic Text on a Base Image.

Hi all I need to combine these two scripts: Firstly, the following decides which out of the following list is selected based on its value in the mySQL table: <select name="pack_choice"> <option value="Meters / Pack"<?php echo (($result['pack_choice']=="Meters / Pack") ? ' selected="selected"':'') ?>>Meters / Pack (m2)</option> <option value="m3"<?php echo (($result['pack_choice']=="m3") ?

How can i save array from inputs, witch is $igraci and it have 5 values, to mysql base, i tryed but in mysql it shows Array. This is form: <form action="dodaj_klan.php" method="post" > <p> <label>Naziv klana:</label> <input name="naziv" type="text" size="20%" /> <label>Web Sajt:</label> <input name="website" type="text" size="20%" /> <label>E-Mail:</label> <input name="email" type="text" size="20%" /> <br /><br /> <label>Igraci klana(5):</label> <input name="lider" type="radio" value="1" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="2" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="3" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="4" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="5" /> <input name="igraci[]" type="text" size="20%" /> <label><i>(obelezi lidera klana)</i></label> <br /><br /> <input class="button" type="submit" name="submit" value="Dodaj" /> </p> </form> Now i wonna save this igraci[] array in mysql, i tried like this but it doesn't work: $igraci = $_POST['igraci']; $query = "INSERT INTO klanovi (naziv, website, email, igraci) VALUES ('{$naziv}', '{$website}', '{$email}', '{$igraci}')"; $result = mysql_query($query, $connection); How can i do this? Thanks.. Using curl_multi, I have loaded up 3 url's and then printed the array. 1) How can I also set a timestamp on output to let me know when each url was run? 2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"?

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? 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. This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=344127.0 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" ),
];

Edited May 27 by AquariaXI 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 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. Hi, A piece of software I'm using an array is made that looks like the following: Code: [Select] [["Select","Vehicle",0.142933,[0.15,0.4,0.05,0.01]]] How would I be best parsing it so: Square brackets currently showing an array becomes an array within PHP Text strings surrounded by "quotations" lose the quotation mark when stored in the PHP array Numbers remain as values in the PHP array The arrays can become quite large, so which would be the best way to go about it? Regards, Jason 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. |
