PHP - Getting Items Out Of Array Inside Class.
Hi,
Im wondering if there is an easy way to get items out of an array returned by a function inside a class. A code example would be: Code: [Select] class modDB { public function getPwdSalt() { $arr = array("salt", "password"); return $arr; } } ?> And what i would like to be able to do is something like: Code: [Select] $modDB = new modDB; echo $modDB->getPwdSalt()->[1]; and just get returned 'password'. Is something like that possible? Many Thanks. Similar TutorialsI tried these below, Code: [Select] class Site extends Controller { function Site() { public $data = Array(); } } but it fail? Thanks in advanced. I have an existing instance of my class Database, now I want to call that instance in my Session class, how would I go about doing this? Ok. I know you can pass the object of a class as an argument. Example: class A { function test() { echo "This is TEST from class A"; } } class B { function __construct( $obj ) { $this->a = $obj; } function test() { $this->a->test(); } } Then you could do: $a = new A(); $b = new B($a); Ok so that's one way i know of. I also thought that you could make a method static, and do this: (assuming class A's test is 'static') class B { function test() { A::test(); } } But that is not working. I'd like to know all possible ways of accomplishing this. Any hints are appreciated. thanks Hi people! class FirstOne{ public function FunctionOne($FirstInput){ //do stuff and output value return $value1; } } Then:- class SecondOne{ public function FunctionTwo($AnotherInput){ //do stuff and output value return $value2; } } What I want to know is this, if I want to use FunctionOne() in Class SecondOne do I do it like this:- (Assume as I have instantiated the first class using $Test = new FirstOne(); ) class SecondOne{ function SecondedFunction(){ global $Test; return $Test->FunctionOne(); } public function FunctionTwo($AnotherInput){ //do stuff and output value return $value2; } public function FunctionThree(){ //some code here $this->Test->SecondedFunction();<--I think as I can omit the $this-> reference } } My point is: Do I have to do it this way or is there way of having this done through __construct() that would negate the need for a third party function? I have a version working, I just think that it is a little convoluted in the way as I have done it, so I thought I would ask you guys. Any help/advice is appreciated. Cheers Rw 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? This probably doesn't matter much, but I am using a 'Display' class for final output to the browser. The class will display the obvious HTML header and then display either the full site or the mobile site. It also displays the CSS / JS (which is previously selected in the page-specific controller code as there are variations based on server-side checks). Basically it is the ONLY class that actually needs to send anything to the browser. When I begin output and echo inside the class, that is the end of the script - there is no more server-side code to execute. If I shouldn;t echo inside the class, is it that bad to do so? Hi, I'm hoping someone can help me with a simply array problem. I have a table with two columns: "ID" and "Name" and 100 Names. I also have an array called $myIDList containing 10 IDs. I want to display 10 Names from the table that correspond with the IDs from my array. Originally, I tried to implode the array, adding commas and inserted into my MySQL query using: $myQuery = "SELECT ID, Name FROM namesTable WHERE ID IN ($myImplodedIDList)"; The problem was that duplicated names (i.e. the same Name, but assiged to different IDs) would only be displayed once. So now I'm trying to use the original array to loop through a second array and display Names where the ID matches an ID from my first array. I have succesffuly listed the table like this: $myQuery = "SELECT ID, Name FROM myTable ORDER BY ID"; $myResult = mysql_query($myQuery) or die(mysql_error()); while($row=mysql_fetch_array($myResult)) { echo $row['ID']; echo $row['Name']; } But I want to do something like: while($row=mysql_fetch_array($myResult)) { while $row['ID'] = $myIDList { echo $row['Name'] } } Can someone shed some light onto this for me please? Thank you! Bryan Well in the class UserValidator I have a public method validate(), which checks the validation type and then calls specific private methods to execute the validation script. It gets a bit tricky here since the method validate() has to decide what private method to call. I am thinking about using call_user_func_array(), the script currently looks like this below: Code: [Select] public function validate(){ // The core method validate, it sends requests to different private methods based on the type if(empty($this->type)) throw new Exception('The validation type is empty, something must be seriously wrong...'); if(is_array($this->type) and !is_array($this->value)) throw new Exception('Cannot have scalar value if the type is an array.'); if(!is_array($this->type) and is_array($this->value)) throw new Exception('Cannot have scalar type if the value is an array.'); // Now we are validating our user data or input! $validarray = array("register", "login", "password", "session", "email", "reset", "profile", "contacts", "friends"); foreach($this->type as $val){ $method = "{$val}validate"; if(in_array($val, $validarray)) call_user_func_array(array($this, $method), array()); } } The method to execute depends on the validation type passed into the validator class, so it is somewhat like a dynamic function call. The problem is, well, I am not sure if I am using call_user_func_array() properly. I read it from php manual that it needs to accept a class instance, but there is no such instance inside a class method so I use $this in the argument. Is this the correct way of using call_user_func_array()? If not, how am I supposed to do this? thanks. Hi, I'm having a bit of a problem understanding why I'm not able to use the class I'm extending off of functions. I have a category class that extends off my core class, inside that category class, I'm able to use the core functions and variables inside all custom functions, but not the __construct function. So, to be clear, inside class class, I'm able to call $this->core->function() inside custom functions, such as function add_parent(), but not the __construct function. Why is this happening, what is the logic behind this? This is how I'm extending the class off of the core class: Code: [Select] <?php $core = new core; $parent = new parents; $parent->core =& $core; ?> With this, like I said, I'm able to use all of my core functions inside all other classes called this way, so inside all of the other classes I can do: Code: [Select] <?php $this->core->function(); ?>everywhere besides __construct(). Do I not have the class called properly? Do I need to pass my core class through differently? How can I fix this? Thanks. I have an array of products. The array has an ID and price. I'd like to know the most efficient way of adding up all the same ID fields in the array. Code: [Select] <?php $items[] = array( 'id' => 1, 'price' => 5.99, ); $items[] = array( 'id' => 2, 'price' => 1.99, ); $items[] = array( 'id' => 3, 'price' => 2.40, ); $items[] = array( 'id' => 2, 'price' => 6.99, ); $items[] = array( 'id' => 4, 'price' => 8, ); $items[] = array( 'id' => 2, 'price' => 3, ); $items[] = array( 'id' => 3, 'price' => 1, ); function add_like_items($items) { //manipulation return $sums; } //$sums would be an array like //$sum[1] = 5.99 //$sum[2] = 11.98 //$sum[3] = 3.40 //$sum[4] = 8 ?> Anybody have suggestions on the best way to go about doing this? How can I check if an array contains two items that are the same? For example ("apples", "bananas", "oranges") returns false But ("apples", "bananas", "bananas") returns true I've searched all over for the past few days trying to figure out what I'm doing wrong. Basically what I'm trying to do is create a prepared statement inside my User class. I can connect to the database, but my query does not execute as expected. Here's the code for my User class Code: [Select] <?php include '../includes/Constants.php'; ?> <?php /** * Description of User * * @author Eric Evas */ class User { var $id, $fname, $lname, $email, $username, $password, $conf_pass; protected static $db_conn; //declare variables public function __construct() { $host = DB_HOST; $user = DB_USER; $pass = DB_PASS; $db = DB_NAME; //Connect to database $this->db_conn = new mysqli($host, $user, $pass, $db); //Check database connection if ($this->db_conn->connect_error) { echo 'Connection Fail: ' . mysqli_connect_error(); } else { echo 'Connected'; } } function regUser($fname, $lname, $email, $username, $password, $conf_pass) { if ($stmt = $this->db_conn->prepare("INSERT INTO USERS (user_fname,user_lname, user_email,username,user_pass) VALUES (?,?,?,?,?)")) { $stmt->bind_param('sssss', $this->fname, $this->lname, $this->email, $this->username, $this->password); $stmt->execute(); $stmt->store_result(); $stmt->close(); } } } ?> And here's the file that I created to instantiate an instance of the user class. Code: [Select] <?php include_once 'User.php'; ?> <?php //Creating new User Object $newUser = new User(); $newUser->fname = $_POST['fname']; $newUser->lname = $_POST['lname']; $newUser->email = $_POST['email']; $newUser->username = $_POST['username']; $newUser->password = $_POST['password']; $newUser->conf_pass = $_POST['conf_pass']; $newUser->regUser($newUser->fname, $newUser->lname, $newUser->email, $newUser->username, $newUser->password, $newUser->conf_pass); ?> And lastly heres the form that I want to get info from the user to insert into the database Code: [Select] <html> <head> <title></title> <link href="stylesheets/styles.css" rel="stylesheet" type="text/css"/> </head> <body> <form action = "Resources/testClass.php" method="post" enctype="multipart/form-data"> <label>First Name: </label> <input type="text" name="fname" id="fname" size="25" maxlength="25"/> <label>Last Name: </label> <input type="text" name="lname" id="lname" size="25" maxlength="25"/> <label>Email: </label> <input type="text" name="email" id="email" size="25" maxlength="40"/> <label>Username: </label> <input type="text" name="username" id="username" size="25" maxlength="32"/> <label>Password: </label> <input type="password" name="password" id="password" size="25" maxlength="32"/> <label>Re-enter Password: </label> <input type="password" name="conf_pass" id="conf_pass" size="25" maxlength="32"/> <br /><br /> <input type="submit" name="submit" id="submit" value="Register"/> <input type="reset" name="reset" id="reset" value="Reset"/> </form> </body> </html> Running a simple query: SELECT team, rank from table ORDER BY rank ASC returns 8 records in order from 1 to 8 I then want to a assign a new variable to each that I can use for later queries ie: team with rank 1 = $team1 team with rank 2 = $team2 team with rank 3 = $team3 etc.... Thanks in advance. Hi guys, I'm just working on a script to get menu items from a database, sorted by a sort column. Each item needs to be checked to see if it has a parent, then paired with the parent. Would it be best to get all of the items at once and pair them with PHP, or get the children of each item when as a separate array? id label link parent sort 1 Home index.php 0 10 2 About about.php 0 20 3 Contact Us contact.php 2 10 Hi all, I have a table that shows data from an xml response that has been converted to an array. I have successfully managed to get that to work but it's showing more items than I want. I'm trying to isolate the items by state. There are 11 or so different states, of which I only want 7. I've tried the following with a while loop but I keep getting the message "undefined index: job_status" Here's my code (partial)
$projects = array();
$xml=simplexml_load_string($response) or die("Error: Cannot create object");
foreach($xml->Jobs->Job as $item) {
$projects[] = array(
'job_no' => (string)$item->ID,
'job_name' => (string)$item->Name,
'job_due' => (string)$item->DueDate,
'job_status' => (string)$item->State,
'job_staff' => (string)$item->Assigned->Staff->Name,
);
}
usort($projects, function($a,$b) {return $a['job_due'] <=> $b['job_due']; } );
$projects = array_reverse($projects);
while ($projects['job_status'] == ('Feasibility')
&& ('Measure Up')
&& ('Model Drawing')
&& ('Concept Design')
&& ('Developed Design')
&& ('Resource Consent')
&& ('Construction Documentation')) {
foreach ($projects as $proj) {
$formatted = date('d/m/Y', strtotime($proj['job_due']));

$job_name ="{$proj['job_name']}";
$job_due ="$formatted";
$job_status ="{$proj['job_status']}";
$job_staff ="{$proj['job_staff']}";
Any help would be much appreciated thanks. Hi guys, I am trying something fairly simple but I'm not sure if this would be a good practice. Basically I am using a big class called CommonLibrary that holds common functions as methods and common variables as static variables. But I have some variables here and there like $allAlphabet = range ('a' , 'z'), that cannot be declared as a property because it gives me a parse error. I don't want to call an object for this class because instancing it is of no use. Values will never change with regards to instances. So the next best thing that I tried was declaring all static variables first, and then changing thei property values inside the class __construct with self::$variable = 'somevalue', and then using this code below to assign values to the empty static variables. $dummyObject = new CommonLibrary; unset($dummyObject); echo CommonLibrary::$staticVariable; // This property is NULL before the constructer is triggered. Anyone recommend any better ways of doing this? Thanks in advance! I have this array of items in my php file.
$items = array(
array("id" => 100,"categorypath" => "level1/powders", "product" => "Mens powder"),
array("id" => 200,"categorypath" => "level1/oils/sunflower", "product" => "XYZ oil"),
array("id" => 300,"categorypath" => "level1/eatable/vegetables", "product" => "carrot"),

Not being an expert in php, I have somehow managed to reach thus far in my code, but can not quite arrive at the correct logic. Having trouble with handling associative arrays and objects in php.

I have now reached a point where I desperately need help from experts.
When I remove 1 session item using this it works fine when I select more than 1 item to be removed I get unexpected results, I have checked the outputted html to see what positions get echoed into the remove check box and they are correct, so I guess the problem lies in my remove code here is the part of the form that sends the remove check box <?php for ($basket_counter=0;$basket_counter<$_SESSION['ses_basket_items'];$basket_counter++) { $price=sprintf("%01.2f",$ses_basket_price[$basket_counter]); $quantity=$ses_basket_amount[$basket_counter]; $code=$ses_basket_stockcode[$basket_counter]; $itemID=$ses_basket_id[$basket_counter]; $name=$ses_basket_name[$basket_counter]; $image=$ses_basket_image[$basket_counter]; $size=$ses_basket_size[$basket_counter]; $sizechoice=$ses_basket_sizechoice[$basket_counter]; // create array from sizes and make the option box selections if ($sizechoice!="" && (!in_array($sizechoice, array('One Size', 'one size', 'free size', 'Free Size', 'Adjustable', 'adjustable')))) { // add size trigger $sizelist="add"; //create the array $sizepick=explode(",", $sizechoice); } else { $sizepick=$sizechoice; } // adjust gst for AU customers if ($country=='AU') { $price=sprintf("%01.2f",($price*1.1)); $unit=sprintf("%01.2f",($price/$quantity)); } else { $unit=sprintf("%01.2f",($price/$quantity)); } ?> <tr> <td align='center' class='rescon' style="border-bottom:solid #330000 1px;"><input type="checkbox" name="remove[<?php echo $basket_counter; ?>]" value="<?php echo $basket_counter; ?>" /></td> and here is the part of the code that processes the removal of the items $remove = $_POST['remove']; if (isset($remove) && ($remove!='')) { foreach($remove AS $key => $remove_position){ array_splice ($ses_basket_name, $remove_position, 1); array_splice ($ses_basket_amount, $remove_position, 1); array_splice ($ses_basket_price, $remove_position, 1); array_splice ($ses_basket_stockcode, $remove_position, 1); array_splice ($ses_basket_image, $remove_position, 1); array_splice ($ses_basket_size, $remove_position, 1); array_splice ($ses_basket_sizechoice, $remove_position, 1); array_splice ($ses_basket_id, $remove_position, 1); $_SESSION['ses_basket_items']--; } } I am using a form with checkboxes named remove[$remove_position] and the positions in the form are correct for each item in the array, but when I select more than 1 item to delete they are not always the correct items only the first 1 selected. What am I doing wrong here?? Quote from: Hollows on August 20, 2010, 11:29:25 AM I have an array that is pulling 10 results from a db like this - <?php $result = mysql_query("SELECT * FROM inbox ORDER BY id DESC LIMIT 0,10"); while ($row = mysql_fetch_array($result)) { <div class="<?php echo $row['class']; ?>"> <?php echo $row['name']; echo $row['message']; ?> </div> basically 'class' is defined in an earlyier part of the script and is used to tell the css what class to display - as I'm sure you can see. What I'd like todo then be able to update the class of a message once I have read it, so update the class table with something like 'read' so the css will then be based on .read not what ever was set by the form, either using a link or form button inside each of the 10 results from the array. I've managed to update one by using - Code: [Select] mysql_query("UPDATE shoutbox SET class = 'read' WHERE id = ''XX"); // XX should be row id But I had to set that myself and point the id to the row id I wanted to change - How can I have that already populated with the row for the id that triggered it? To be clear so it looks like - Name Message read button _____________ Name Message read button _____________ Name Message read button _____________ and so on... Would I be better going by check boxes and one submit button? If so how could I implement that? I can provide the full code I've written if it helps Thank you in advance I'm new at PHP and have a problem. I have a MySql database with lists of students grouped into classrooms. A typical group is shown in the attached screenshot screenshot.docx. I want to be able to select one or more of the names by using the associated checkbox, and upgrade a student or students into a different group as defined in the radio button list also in the screenshot. I have the rudiments of the file attached, but I have absolutely no idea how I can post the array so that the records are updated. Each student has an individual record with a field name userGroup which holds a string nominated by their classroom teacher, such as "year7", "year 8" and so on while they are in one of the several classrooms, but when they leave school this is recorded in a field named noGroup with a value of 0 or 1. I can post further details as required, but it would be great if someone could help me. |
