PHP - Data From Array Inside A Function - Help!
I thought this would be fairly straightforward but for some reason isn't working.
I have an array built from some MySQL data: - Code: [Select] $all_products[1] = array( "title"=>"widget", "product_code"=>"wid-123", "colour"=>"blue"); $all_products[2] = array( "title"=>"thingy", "product_code"=>"thi-345", "colour"=>"red"); This works fine when used like: - echo 'Product #1 is a ' . $all_products[1]['colour'] . $all_products[1]['title'] . ', code: ' . $all_products[1]['code']; Gives: "Product #1 is a blue widget, code: wid-123" However, if I do this: - function showproductinfo($thisproduct) { echo 'Product #' . $thisproduct . ' is a ' . $all_products[$thisproduct]['colour'] . $all_products[$thisproduct]['title'] . ', code: ' . $all_products[$thisproduct]['code']; } showproductinfo(1); It gives nothing Can I use a variable passed via a function as the array key in this way? If so, how? And if not, what's the best way to do what I, trying to do? Similar TutorialsHello all, What I'm trying to do is insert dynamic data supplied by the user into an array, but for some reason, the loop only builds arrays inside of arrays (or so it seems) and doesn't create an array with unique indexes and associated data. I was hoping someone could point me in the right path? I've searched numerous forums, threads and google but cannot find an answer. Here is the code snippet I'm working on. What it's supposed to do is collect a user's input, which is a Quantity amount and a high number, and based on that amount, create an array of random integers. This is my latest attempt. Now, maybe I'm just losing it, but when I place print_r($output) inside the loop, I see how it's being created but no unique indexes, just nested arrays. When I place it outside of the loop, I only receive one array with one index and value even though a high quantity was sent to the script. Code: [Select] $i = 1; while ($i <= $Quantity){ $output = array(rand($RandLow, $RandHigh)); $i++; } print_r($output); Here is another attempt, which again proved to be unsuccessful, at least to my tire brain. Code: [Select] $i = 1; while ($i <= $Quantity){ $output = rand($RandLow, $RandHigh); $total = array($output); $i++; } print_r($total); I've tried the for() loop as well but I just can't seem to make heads or tails of this and I'm sure it's going to be something simple that I'm missing. Thanks in advance for any help and insight if you know a better way to do this. The Script:
$desired_width = 110;
if (isset($_POST['submit'])) {
$j = 0; //Variable for indexing uploaded image
for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array
$target_path = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/uploads/"; //Declaring Path for uploaded images
$validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
$ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.)
$file_extension = end($ext); //store extensions in the variable
$new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
$target_path = $target_path . $new_image_name;//set the target path with a new name of image
$j = $j + 1;//increment the number of uploaded images according to the files in array
if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
&& in_array($file_extension, $validextensions)) {
if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
$tqs = "INSERT INTO images (`original_image_name`, `image_file`, `date_created`) VALUES ('" . $_FILES['file']['name'][$i] . "', '" . $new_image_name . "', now())";
$tqr = mysqli_query($dbc, $tqs);
// Select the ID numbers of the last inserted images and store them inside an array.
// Use the implode() function on the array to have a string of the ID numbers separated by commas.
// Store the ID numbers in the "image_file_id" column of the "thread" table.
$tqs = "SELECT `id` FROM `images` WHERE `image_file` IN ('$new_image_name')";
$tqr = mysqli_query($dbc, $tqs) or die(mysqli_error($dbc));
$fetch_array = array();
$row = mysqli_fetch_array($tqr);
$fetch_array[] = $row['id'];
/*
* This prints e.g.:
Array ( [0] => 542 )
Array ( [0] => 543 )
Array ( [0] => 544 )
*/
print_r($fetch_array);
// Goes over to create the thumbnail images.
$src = $target_path;
$dest = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/thumbs/" . $new_image_name;
make_thumb($src, $dest, $desired_width);
} else {//if file was not moved.
echo $j. ').<span id="error">please try again!.</span><br/><br/>';
}
} else {//if file size and file type was incorrect.
echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
}
}
}
Hey, sorry that I am posting this darn image upload script again, I have this almost finished and I am not looking to ask more questions when it comes to this script specifically.
With the script above I have that part where the script should store the ID numbers (the auto_increment column of the table) of the image files inside of one array and then the "implode()" function would get used on the array and then the ID numbers would get inserted into the "image_file_id" column of the "thread" table.
As you can see at the above part the script prints the following:
Array ( [0] => 542 )
Array ( [0] => 543 )
Array ( [0] => 544 )
And I am looking to insert into the column of the table the following:
542, 543, 544I thought of re-writing the whole image upload script since this happens inside the for loop, though I thought maybe I could be having this done with the script as it is right now. Any suggestions on how to do this? Hello all, I have some piece of code that is nested like this $variable = 'This is a global argument'; function parentFunction($variable) { function childFunction() { echo 'Argument of the parent function is '.$GLOBALS['variable']; } childFunction(); } parentFunction(5); What I want to know is - Is there a way to access a variable from the parent function without passing arguments to the child function? (Something like how classes have parent::?). I don't want to use $GLOBALS because it might cause some variable collision, and I didn't want to pass arguments because incase I decide to change the arguments in the parent function I'd have to do it in the child function aswell. From my searching around in the Internet it seems like this is not possible, but if theres a slight chance that there might be something out there, i'm willing to give it a shot . Thanks in advance When I put this chunk of code into it's own function: function fetch_all ($dbc, $query) { include ('knuffix_list_func.php'); pagination_start ($dbc, $query); $offset = $pag_array[0]; $rows_per_page = $pag_array[1]; $query = $query . " LIMIT $offset, $rows_per_page"; echo "test query: " . $query; knuffix_list ($query, $dbc); pagination_end ($pag_array); } And when I echo out the query as you can see in the example, then I notice that the variables $offset and $rows_per_page never get appended. I set the variable $pag_array to a global inside the function pagination_start(). It usually works when I DON'T wrap a function around this chunk of code, but if I do wrap a function around everything then the global suddenly won't work anymore. Btw, this also won't work if I wrap a function around the function DECLARATIONS. Any ideas, how I could make it work? I'm creating a tool for building project proposals for clients, with pricing. I have a database with two tables: services and clients. The services table looks like this: Code: [Select] | code | name | cost | +-------------+-------------+------+ | logo_design | Logo design | 10 | | web_design | Web design | 20 | The clients table looks like this: Code: [Select] | id | client | logo_design | web_design | +----+---------+-------------+------------+ | 1 | Walrus | yes | yes | | 2 | Narwhal | no | yes | How would I link the results from these two tables so that I only pull out the services each person wants from the database? Here is what I have so far: Code: [Select] <? $sql = "SELECT * FROM services"; $result = mysql_query($sql); while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) { echo $row{'name'} . ': $' . $row{'cost'} . '<br />'; } ?> This, of course, displays all the services, with all the prices, like so: Logo design: $10 Web design: $20 I want to add something here so that based on the selected client, we see only the services/prices they selected (ol' Narwhal's page would not show the "Logo Design" line). I've got the data from "clients" pulled in to this page as well, but don't know how to relate it to "services." Thanks in advance! Let me know if I've left out any info that would help you to point me in the right direction. im using a function which connects to a db called 'comments' and then inside that function i again called another function that will connect to the db 'main' to get avatars.... but as i put Code: [Select] mysql_select_db("main") or die(mysql_error()); on the new function, the original function stops to fetch rows. i tried to remove "mysql_select_db("main") or die(mysql_error());" and used the new function to return some text only and it worked, so i guess the connection to the db was the problem... i tried doing Code: [Select] mysql_query("SELECT * FROM main.avatar INNER JOIN main.list ON main.avatar.title=main.list.id WHERE main.avatar.page_id='$id'"); but it also didnt work Hi, after banging my head against the wall for a while thinking this would be a simple task, I'm discovering that this is more complicated than I thought. Basically what I have is a link table linking together source_id and subject_id. For each subject there are multiple sources associated with each. I had created a basic listing of sources by subject... no problem. I now need a way of having a form to create an ordered list in a user-specified way. In other words, I can currently order by id or alphabetically (subject name lives on a different table), but I need the option of choosing the order in which they display. I added another row to this table called order_by. No problem again, and I can manage all of this in the database, however I want to create a basic form where I can view sources by subject and then enter a number that I can use for sorting. I started off looping through each of the entries and the database (with a where), and creating a foreach like so (with the subject_id being grabbed via GET from the URL on a previous script) Code: [Select] while($row = mysqli_fetch_array($rs)) { //update row order if (isset($_POST['submit'])) { //get variables, and assign order $subject_id = $_GET['subject_id']; $order_by = $_POST['order_by']; $source_id = $row['source_id']; //echo 'Order by entered as ' . $order_by . '<br />'; foreach ($_POST['order_by'] as $order_by) { $qorder = "UPDATE source_subject set order_by = '$order_by' WHERE source_id = '$source_id' AND subject_id = '$subject_id'"; mysqli_query($dbc, $qorder) or die ('could not insert order'); // echo $subject_id . ', ' . $order_by . ', ' . $source_id; // echo '<br />'; } } else { $subject_id = $_GET['subject_id']; $order_by = $row['order_by']; $source_id = $row['source_id']; } And have the line in the form like so: Code: [Select] echo '<input type="text" id="order_by" name="order_by[]" size="1" value="'. $order_by .'"/> (yes I know I didn't escape the input field... it's all stored in an htaccess protected directory; I will clean it up later once I get it to work) This, of course, results in every source_id getting the same "order_by" no matter what I put into each field. I'm thinking that I need to do some sort of foreach where I go through foreach source_id and have it update the "order_by" field for each one, but I must admit I'm not sure how to go about this (the flaws of being self-taught I suppose; I don't have anyone to go to on this). I'm hoping someone here can help? Thanks a ton in advance This has been bothering me for a while, how do I do this? echo (" <form method = 'get' action = 'member.php?action=Search&option=faction&name=NAME'> Faction's Name: <input type='text' name='member' /><br /><br /> <input type='submit' value='Search' /> </form> "); name='member' is supposed to be sent with he member.php?action=Search&option=faction&name=NAME. Obviously replacing NAME with the input. Ok I am not sure if this is possible but I hope someone out there can show me a way. I have a webpage with left content boxes that are looped in depending on the sql info. In one of the boxes the content of the box is going to be another page being pulled in. Now normally I would just put in the include ("page"); but its inside of an echo so you would end the echo do the include and then start the echo back up, however in this case its pulling in the coding from a variable so im a bit lost as to what to do now. The page would have something like... Code: [Select] echo ' '.html_entity_decode(stripslashes($info[content])).' '; and the info content part is Code: [Select] include("pages/paypalbox.php") I've tried making the variable Code: [Select] '; include("pages/paypalbox.php"); echo' Hoping that would fix it but I should of known better, the variable is being pulled in so its not processing it as part of the first step coding and it isn't going to do anything other then print it out like text. So is there a way to make this work? Thanks. Hi, I'm an novice/intermediate PHP prgogrammer, so excuse me if this is a stupid question. I have one php program that consist of a few functions. Inside the function taht is the starting point I pickup a few entries from a MYSQL database, and display those in my html page. I wish to dynamically put a link on those entries that makes it possible for the users to click those entries an get directed to other functions inside this very same PHP program WITH a parameter. The parameters that should accompany the url/link into the selected function to be able to select apropriate records from the mysql tables. Any hints and tips for this would be highly appreciated! Kind Regsrds, Terje Hvidsten. I dont know why I'm having so many problems with this. I need to get a variable that defined in an included file inside of a function I've got this Inside file.php I've got the $variable1 and $variable2 defined (they're dynamic/different to each user) include('file.php'); function foo() { GLOBAL $variable1, $variable2; echo $variable1; echo $variable2; } foo(); Yet it outputs nothing? If I Include file.php right inside of the function it works however. Any idea? Hi Everyone. I'm working on a form, that allows the user to select the country / county / area where they are from. I am doing this using: - mysql database store the locations in - PHP OOP, to pull this information from the database - AJAX/Javascript to only show the next dropdown, once the first dropdown has been selected. Example: select country then the county dropdown will appear, select county then the area/town will appear. However, the first drop down for country is placed directly on to the page. So the javascript works fine. but the second dropdown is placed in to a PHP function, and the javascript seems to no longer want to work. CODE: Code: [Select] //////////////// CODE FOR COUNTRY /////////// if(isset($_REQUEST['country'])) { echo ' <div class="labelleft">County / State:</div> <div class="fieldleft"> <div > <select name="county" id="county" onchange="javascript:AJAXQuery("lib/search.php?town="+this.value, "tw", "")"> <option value="0">Select County</option> <option value="0">-------</option>'; $countyList = Area_county::find_country_id($_REQUEST['country']); foreach($countyList as $countyLists){ $county_id = $countyLists->id; $county_list = $countyLists->county; echo '<option value="'.$county_id.'">'.ucwords($county_list).'</option>'; } echo ' </select> </div> </div> <div class="clear"></div>'; } Any ideas? Thanks I have included language file and function file in my index.php
include 'includes/functions.php'; include 'languages/english.php';english.php contains <?php $lang['success']['a'] = 'Settings have been updated.'; $lang['error']['b'] = 'Database error. Please try again later!'; ................................. ?>functions.php
<?php
function testFunction($id, $settings, $db){
$query = 'UPDATE table_name SET a = a + :a WHERE id = :id';
$update = $db->prepare($query);
$update->bindParam(':a', $settings['a'], PDO::PARAM_INT);
$update->bindParam(':id', $id, PDO::PARAM_INT);
$success = $update->execute();
if($success){
print $lang['success']['a'];
}else{
print $lang['error']['b'];
}
}
.................................................

Now if i print testFunction(); i got Undefined variable: lang in ............. If i include 'languages/english.php'; in testFunction() then everything works. Any other way to make $lang working without including language file in testFunction(). (Sorry for my bad english)
print testfunction(2, $settings, $db); Hey Before I start playing around with some code I want to know if it is possible to call a function inside a while loop that will call echo a some stuff then return to the loop it got called by? thanks hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped. Using curl_multi, I have loaded up 3 url's and then printed the array. 1) How can I also set a timestamp on output to let me know when each url was run? 2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"? Code <?php function multiRequest($data, $options = array()) { // array of curl handles $curly = array(); // data to be returned $result = array(); // multi handle $mh = curl_multi_init(); // loop through $data and create curl handles // then add them to the multi-handle foreach ($data as $id => $d) { $curly[$id] = curl_init(); $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d; curl_setopt($curly[$id], CURLOPT_URL, $url); curl_setopt($curly[$id], CURLOPT_HEADER, 0); curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1); // post? if (is_array($d)) { if (!empty($d['post'])) { curl_setopt($curly[$id], CURLOPT_POST, 1); curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']); } } // extra options? if (!empty($options)) { curl_setopt_array($curly[$id], $options); } curl_multi_add_handle($mh, $curly[$id]); } // execute the handles $running = null; do { curl_multi_exec($mh, $running); } while($running > 0); // get content and remove handles foreach($curly as $id => $c) { $result[$id] = curl_multi_getcontent($c); curl_multi_remove_handle($mh, $c); } // all done curl_multi_close($mh); return $result; } $data = array(array(),array()); $data[0]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json'; $data[1]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json'; $data[2]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json'; $r = multiRequest($data); print_r($r); ?> Output Array ( => Pearl Jam [1] => Black Eyed Peas [2] => Nirvana ) Preferred Output 01:00:01 Pearl Jam 01:00:02 Black Eyed Peas 01:00:03 Nirvana Hi, I have a (probably quite simple) question about passing form data to a php script that contains an iframe with another php script that also needs some of this form data. Basically, my problem is as follows: I have the following code in a file called example1.php: Code: [Select] <html> //some html stuff <?php if(isset($_POST['from'])) {$from1 = $_POST['from'];} else {$from1 = 'English';} $langList = array('English', 'French', 'German', 'Dutch'); print('<select id="from" name="from">'); foreach ($langList as $lang) {printf('<option %s>%s</option>', ($from1 == $lang ? 'selected="selected"' : ''), $lang); } echo '</select>'; ?> //some more html stuff </html> As you can see, it retrieves a variable via POST and selects its value from a list. The variable is posted from an html file (example0.htm) containing the following: Code: [Select] <form method="post" action="example1.php"> This worked fine, until I put example1.php inside an iframe in example2.php as follows: Code: [Select] <html> //some html here <?php //some php here ?> <iframe src ='example1.php' id='something' name='something' > </iframe> </html> and changed: "post" action="example2.php" in my html form. My question is: how do I pass form data from example0.htm to example2.php to example1.php, so that example2.php gets loaded when the submit button on my form gets pressed, but so that example1.php (which gets loaded from the iframe in example2.php) can also access the form data? Thanks! hello. i have two functions that are not working because i cant seem to input the php and java correctly.. could someone help please. how do i put these lines into a function: 1 - Code: [Select] function applyBox() { echo ' <div id="apply"> <h3><b><span class="arial18_GRN">Apply NOW</span> to become a<br>BusinessMobiles.com Affiliate</b></h3> <p class="applyText">Drive quality traffic to one of our<br>partners and get paid for it.</p> <a href="#" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('Apply','','image/callsToAction/applyButton2.jpg',1)"> <img src="image/callsToAction/applyButton1.jpg" class="applyButton" alt="Apply" name="Apply" width="137" height="36" border="0"></a> </div> '; } this part is not working: onMouseOver="MM_swapImage('Apply','','image/callsToAction/applyButton2.jpg',1)"> i can see that the ' is breaking it. i tried putting .'s but it didn't work : onMouseOver="MM_swapImage('.Apply.','..','.image/callsToAction/applyButton2.jpg.',1)"> 2 - this form: Code: [Select] <div class="form"> <form name="Form" method="post" action="<?PHP echo $_SERVER['PHP_SELF']; ?>"> <input name="submit" type="hidden" value="submit" /></input> <input type="text" class="inputField" name="Uname" id="Uname" value="'.$Uname.'" onfocus="clearUname()"></input> <input type="text" class="inputField" name="PW" id="PW" value="'.$PW.'" onfocus="clearPW()"></input> <input type="image" class="submit" src="image/wrapper/submit.jpg" value="Submit" alt="login" width="36" height="20" border="0" /></input> </form> this part is not working : <form name="Form" method="post" action="<?PHP echo $_SERVER['PHP_SELF']; ?>"> i tried: <form name="Form" method="post" action="'.echo $_SERVER['PHP_SELF'].'"> but no luck. any suggestions ???? thanks ricky Hi I am trying to use the nl2br function like this
while ($row = mysqli_fetch_array($query)) {
//May need this later to output pictures
// $imageURL = 'upload/'.rawurlencode($row["filename"]);
echo
" <div class='divTableRow'>
<div class='divTableCell'>{$row['User']} ;</div>
<div class='divTableCell'>nl2br({$row['CommentText']});</div>
</div>
\n";
}
However the output just looks like the attached picture. When I check in the sql db I can see the line breaks when doing a select * from Table ;
I'm using this line a lot on my site. It would be nice if I didn't have to change it 10 times over when I decide to change something. Can I wrap that into a Function and use it in a While loop? echo '<div><a href="/tag/'. strtolower($nameFirst) . '-' . strtolower($nameLast) .'">'. $nameFirst . ' ' . $nameLast .'</a>, '; I have this above it in the While loop.
$nameFirst = $row['nameFirst'];
My function predictably looks like this...
function player_name () {
echo '<div><a href="/tag/'. strtolower($nameFirst) . '-' . strtolower($nameLast) .'">'. $nameFirst . ' ' . $nameLast .'</a>, ';
}
