PHP - How Do I Pass Arguements Into Function & Set Variables Inside?
I have the array defined and print_r (outside the function is show what I need...)
However, I need to somewhay pass those three arguments - name, price, shipping (keys & values) into the "all_products" function and assign (inside the function) each element to a variable {name, price, shipping}. Code: [Select] function all_products($key,$value) { # This is where I'm lost - I know the values are passed to the function but how to I assign them to below variable? echo "$name"; echo "$price"; echo "$shipping"; // Products array defined to send values into "all_products" function & loop to display item name & individual pricing (using WHILE LOOP) $products = array('Product1' => array ( 'name' => 'item one', 'price' => '30.00', 'shipping' => '0.00'), 'Product2' => array ( 'item two', 'price' => '19.50', 'shipping' => '0.10'), 'Product3' => array ( 'item three', 'price' => '21.99', 'shipping' => '0.10') ); while (list($keys, $values) = each($products)) { while (list($k, $v) = each($values)) echo "Checking Looped Data Outside Function: <strong>$k: </strong> $v<br/>"; # echo "<pre>"; # print_r($value); # echo "</pre>"; # Trying to send array elements into "all_products" function & echo (name, price, shipping) keys and values inside that function all_products($k,$v); } Similar TutorialsHello everyone, Can someone show me a way how to pass $_post variable from a form to a function? So, input username and input password to a function login($username, $password). Hello all, I have a 14 column csv that I load into an array, retrieving only the required fields, load the array into columns and perform a sort: Code: [Select] foreach ($array as $key => $row) { $firstname[$key] = $row["firstn"]; $lastname[$key] = $row["lastn"]; $address1[$key] = $row["addr1"]; $address2[$key] = $row["addr2"]; $address3[$key] = $row["addr3"]; $city[$key] = $row["cit"]; $stateprov[$key] = $row["state"]; $country[$key] = $row["cntry"]; $membernumber[$key] = $row["num"];} array_multisort($membernumber,$lastname,$firstname,$address1,$address2,$address3,$city,$stateprov,$country,$array);When I pass say the first three letters of a last name ($find = "smi"), all records matching the search criteria are returned: Code: [Select] foreach ($array as $key => $row) { if (strncasecmp($find, $lastname[$key], strlen($find)) == 0) { echo "<tr><td>" . $firstname[$key] . "</td>"; echo "<td>" . $lastname[$key] . "</td>"; echo "<td>" . $address1[$key] . "</td>"; echo "<td>" . $address2[$key] . "</td>"; echo "<td>" . $address3[$key] . "</td>"; echo "<td>" . $city[$key] . "</td>"; echo "<td>" . $stateprov[$key] . "</td>"; echo "<td>" . $country[$key] . "</td>"; echo "<td>" . $membernumber[$key] . "</td></tr>" . chr(13); }}}So far so good. However, I'd like to put the search part into a function so I can call it a number of times without having to reload the entire csv: Code: [Select] function FindMember() { foreach ($array as $key => $row) { if (strncasecmp($find, $membernumber[$key], strlen($find)) == 0) { echo "<tr><td>" . $firstname[$key] . "</td>"; echo "<td>" . $lastname[$key] . "</td>"; echo "<td>" . $address1[$key] . "</td>"; echo "<td>" . $address2[$key] . "</td>"; echo "<td>" . $address3[$key] . "</td>"; echo "<td>" . $city[$key] . "</td>"; echo "<td>" . $stateprov[$key] . "</td>"; echo "<td>" . $country[$key] . "</td>"; echo "<td align='right'>" . $membernumber[$key] . "</td></tr>" . chr(13); }}}}The search criteria would come from a second txt file with every line containing 2 numbers, separated by a comma: Code: [Select] foreach ($lines as $member => $numbers) { $exploded = explode(",", $numbers); $find = $exploded[1]; FindMember();here $exploded[1] corresponds to $membernumber[$key], so this is where I would call the function, but this is where I run into trouble, nothing gets returned. Does this have something to do with the scope of variables inside a user-defined function? I'd appreciate it if someone could point me in the right direction. TIA I am trying to pass a variable from inside of a function in a file that is included eg include.php Code: [Select] <? function noms(){ $foobar = "apples"; } ?> main.php Code: [Select] <? include("include.php"); noms(); echo "these ". $foobar. " are most delicious... OM NOM NOM"; ?> I am essentially using a include file for a mysql connection and based on the connection outcome i am either setting a value to true or false. It prints "Connected succesfully" and what not just fine, but, after that it wont pass on the variables data. I know its the function because, it passes the data if i put the variable before the function... i just dont get it.. any help would be great. Thanks.

I am trying to build a website, whe
1) User logs in (UserA)
2) Inserting a name in the search box and pressing "Search", a list of all users matching that name is shown
3) The user selects a user (UserB) from that list (among several results)
4) By selecting the user (UserB) , a message box appears to insert text
5) The user(UserA) types the message
6) The user(UserA) presses the SUBMIT button and sends the message to the other user(UserB)
The problem i face is how to pass the variables from my PHP script to the JavaScript script. Its easy for me to get the values of input fiedls, select fields or any other DOM element value. But if the value i need to pass to Javascript file to perform an AJAX call isnt inside a DOM element, how do i do it?
For example, for me to determine the user that will send the message (userA), i will need several data. This data, i have them inside the PHP script as variables, but dont know how to pass them to Javascript file.
Getting the data from the URL, or from a hidden input field or any other DOM element, is a solution, but i want to know the way that is safer and better.
To summarize:
[PHP Script with necessary data]-->[pass necessary data from PHP to JavaScript file]-->[perform an AJAX call] --> [return data to PHP Script]
How do i do it?
Thanks in advance.

Hello, I am new to PHP and would like to know what I am doing incorrectly. I have designed a login form which contains two variables: the username and the password. So for the username: <input type="hidden" name="email" id="email" value="example_username"> And for the password: <input type="password" name="password" id="password" size="15"> I then created a php script which I want to pass the variables "email" and "password" to the e-mail address: <?php { $message = "$email"; $message2 = "$password"; mail ("email@myserver.com", "Hello", $message, $message2); } ?> This should happen through the command: <action="http://www.myserver.com/myscript.php" method="post"> All I get is a blank email with the subject "Hello". Why are the email and password variables not being passed to my email by the php script? Thanks. I have a form, where I'm collecting registration info - like name, address, email, password. I'm calling another php file at server side code, where it will check whether the email exists or not. Pretty simple, just receiving those post variables and check with the database. The issue, if I find a match, I want to go back to the registration.php page, using the following code: if ($email_already_use == "y") { $_SESSION['ERROR'] = "Error"; $_SESSION['MESSAGE'] = "This email address already used. Please try another"; header("location: ".$settings['site_url']."registration.php"); exit; } Now, I would like to place the user input at the registration.php file, but I do not want to use pass variable at URL like this: header("location: ".$settings['site_url']."registration.php?".name=$name&address=$address&email=$email; Is there anyway, I can retrieve those variables at registration.php, without specifying .name=$name&address=$address&email=$email ? Thanks for your help. I see some sites has similar implementation, but did not find anything like how to do it. I have a search page that then submits to a php page that queries the database. I've been struggling to figure out how to paginate it, but I think I've narrowed down the problem. I didn't realize $_POST results didn't pass through when people clicked the pagination links at the bottom. I verified this by replacing the LIKE variable with a specific word and it worked. I'm trying to learn how to set up sessions, thinking this might solve my problem. Doesn't seem to be working. Can I get some suggestions on how to do this? What's happening now is that it's pulling a random 8 pages that have nothing to do with the original query. I start my entire page with: Code: [Select] <?php session_start(); $_SESSION['leafshape'] = $_post['select1']; $_SESSION['leafcolor'] = $_post['select2']; $_SESSION['leafvein'] = $_post['select3']; $_SESSION['leafmargin'] = $_post['select4']; $leafshape = $_SESSION['leafshape']; $leafcolor = $_SESSION['leafcolor']; $leafvein = $_SESSION['leafvein']; $leafmargin = $_SESSION['leafmargin']; and I'm setting up the queries like this: Code: [Select] $query = "SELECT COUNT(*) as num FROM descriptors JOIN plantae ON (descriptors.plant_id = plantae.plant_name) WHERE descriptors.leaf_shape LIKE '{$_SESSION['leafshape']}' AND descriptors.leaf_venation LIKE '{$_SESSION['leafvein']}' AND descriptors.leaf_margin LIKE '{$_SESSION['leafmargin']}'"; I also tried replacing the '{$_SESSION['leafshape']}' in the query with the assigned variable $leafshape Before, if I wanted to send a welcome letter when a user registers i'd do this. $body = "<inserted html code>"; mail('email@email.com', 'Subject', $body, $headers); Now that I am advancing in PHP, I was trying a different method, because when I did the above method, I would have to take all the HTML out of the variable to change something, like an image link, etc... I have tried doing another method, where I can actually leave all the HTML code in a separate file, so that I can easily edit it, and tried 3 things... This one works, but it doesn't pass variables: $body = file_get_contents("emailTemplate.inc.php"); mail('email@email.com', 'Subject', $body, $headers); When I do this one, the page actually just shows on the current page (naturally): $body = include("emailTemplate.inc.php"); mail('email@email.com', 'Subject', $body, $headers); Of course, this has the same effect as the include function: $body = require("emailTemplate.inc.php"); mail('email@email.com', 'Subject', $body, $headers); So my question is, how do I send a formatted HTML email, and pass variables to it, so I can personalize it by the persons name, etc, without adding the HTML to a variable, and so that I can easily update the page whenever I want, and without taking it out of the variable, and sticking back in the edited code? Any help would be appreciated! I would also like to say that I am using this code for the $headers variable too: $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; $headers .= 'From: from@email.com <email@email.com>' . "\r\n"; Thank you in advanced! I want to query a database (search) and pass the desired columns from the search results to another page like so: Code: [Select] <?php //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); //authenticate user require('auth.php'); if (isset($_POST['submit'])) { // Connect to the database. require_once ('config.php'); //Query the database. $sql = "SELECT* FROM members INNER JOIN images ON members.member_id = images_member_id WHERE members.ethnicity = '{$_POST['ethnicity']}'"; $query = mysql_query($sql); if(mysql_num_rows($query) > 0){ while(($row = mysql_fetch_assoc($query)) !== false) { //Redirect to search results page. header("Location: search_results.php?friend='.$row['member_id'].'&me='.$_SESSION['id'].' &pic='.$row['image'].'&name='.$row['username'].'"); } } else { //If no results found. echo 'No results match this search query.' ; } } ?> I get the following error when i try to run the page (by submitting a form from another page which executes this page): Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/a4993450/public_html/profile_search.php on line 31 The culprit line is this one: header("Location: search_results.php?friend='.$row['member_id'].'&me='.$_SESSION['id'].' &pic='.$row['image'].'&name='.$row['username'].'"); As you can see, I eliminated all white space between the variables and concatenations, thinking that that was the problem but I keep getting the error message. I'm at a loss about what to do next. Any help? Hi guys, I have a problem with the print out method.

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 Cant seem to figure this one out for a chained script. In the code below I need to take the value of $drop_var from function drop_1() and send it to function drop_2() So I can add it to the Where clause to limit the results of the third box a little more.

Code: [Select] ; this is a comment var2 : variable ; another comment var3 : file.txt how would I be able to do <?php echo $var2; ?> That would echo "variable" and <?php $file = file($var3); ?> So its reading the file to get the variable from the text file and if the line starts with ";" its disregarded.. Thanks Hi, Im trying to pass a variable ($in_this_instance) into, and then back out of a function. The variable goes into the function no problem, and is echo'ed out fine. However the echo after the close of the function, does not give anything out. Code: [Select] $in_this_instance = 'boo'; function in_this_instance($data) { global $in_this_instance; echo $in_this_instance; $in_this_instance = 'hoo'; $rep_val = '[front banner]'; $test = strpos($data, $rep_val); if ($test === false) { return $data; } else { return $data;; } } add_filter('the_content', 'in_this_instance'); echo $in_this_instance; Could any one give me a pointer please? Many Thanks! Hi guys, I have a trouble with my php snippet, when I insert the var function in the url bar something is like: http://www.mysite.com/delete.php?favorites&id=0 or http://www.mysite.com/delete.php?whateveritis&id=0 It doesn't get pass the favorites function to delete the id. It is the same things that it goes for each different function. Here's the current code: <?php Code: [Select] session_start(); define('DB_HOST', 'localhost'); define('DB_USER', 'mydbuser'); define('DB_PASSWORD', 'mydbpass'); define('DB_DATABASE', 'mydbtablename'); $errmsg_arr = array(); $errflag = false; $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } $db = mysql_select_db(DB_DATABASE); if(!$db) { die("Unable to select database"); } function clean($var){ return mysql_real_escape_string(strip_tags($var)); } $favorites = clean($_GET['favorites']); $id = clean($_GET['id']); if($favorites && $id == ''){ // both are empty $errmsg_arr[] = 'favorites id are missing.'; $errflag = true; } if($errflag) { $_SESSION['ERRMSG_ARR'] = $errmsg_arr; echo implode('<br />',$errmsg_arr); } else { $insert = array(); if(isset($_GET['id'])) { $insert[] = 'id = \'' . clean($_GET['id']) .'\''; } if(isset($_GET['favorites'])) { $insert[] = 'favorites = \'' . clean($_GET['favorites']) . '\''; } if($favorites && $id) { mysql_query("DELETE FROM favorites WHERE id='$id'"); $deleted = mysql_affected_rows(); if($deleted > 0) { echo "favorites channels is deleted"; } else { echo("favorites is already deleted"); } } } ?> If you do know how to get pass the favorites function, then please say so as i need your help. Any advice would be much appreicated. |
