PHP - Why Does __call Pass Arguments And Also An Empty Array? Php5.3
In my view file, I instantiate User class and call two methods that have not been declared or initialized in the class:
$user = new Models\User(); $user->setFirstName('John'); $user->setLastName('Merlino'); echo $user->getFirstName() . " " . $user->getLastName(); However, I have two private members only available to instances: protected $first_name; protected $last_name; Because I don't want to manually create privileged getters and setters for each of my private members, I use the call method: public function __call($name,$args){ echo $name . "<br />"; echo $args . "<br />"; } Because my methods were not initialized, the interpreter calls the __call method as a last option resort, and passes the name of the method in local variable $name and if exists the arguments passed into the method in local variable $args. Ok so that makes sense. However, when I echo the values of the two variables, I see a blank array created: setFirstName Array setLastName Array getFirstName Array getLastName Array See everytime I call it, there's an array being created. I don't see the purpose of this. Also how often do you use __call() in your php applications, specifically when using MVC? Thanks for response. Similar TutorialsI need someone to explain how to loop through an array ($products) and grab the three values (name, price, & shipping) and have them sent to "all_products" function - see line 13 then 61 thru 64. I currently have the script partially working by using array_shift which I know is removing the 1st element (name or $product value). Note: this is the problem (I need $product included in the call to the "all_products" function along with $price & $shipping so that the final output looks as follow: --------------------------------- Checkout Below is a summary of the products you wish to purchase, along with totals: * Candle Holder: $12.95 * Coffee Table: $99.5 * Lamp: $42.99 Total (including tax and shipping): $182.12 ------------------------------------------------------ HERE'S THE SCRIPT FOR REVIEW & COMMENT: =============================== <B>Checkout</B><br> Below is a summary of the products you wish to purchase, along with totals: <?php /* Fix this code by creating a function to determine sub-totals for each product.

What do I need to know to write a code that will not pass an empty variable to my table? Do I use sprint? If I have a parameter that has a default value, how do I pass nothing such that it uses the default value? Passing NULL does not work. Code: [Select] function test($to = "test@test.com", $from) { echo $to . "<BR>" . $from; } //This will NOT show "test@test.com" but instead an empty line test( NULL, "fake@fake.com" ); I have a small php upload/download script, it always worked on older php4 -5 but not on php5.3 ,gobal varitables must be on , I dont know to much about php and was hoping someone will look at at and let me know what to change to make it work on php5.3 or higher..............................THANKS! for any help in fixing this issue

Edited by Ch0cu3r, 01 September 2014 - 06:05 AM. __call is used when a method has been called, is there anything similar to __call but for properties? I wanted to use __get, but that is only for private properties... Hi there every one, i'm writing a class that create instances of other classes and I want to use the __call() magic method to make it more compact and dynamic. here is a basic example of what I'm trying to achieve. The code bellow is the working code. Code: [Select] <?php class creator{ private $objects = array(); public function createObj1($param1, $param2, $param3){ $this->objects[]=new Obj1($param1, $param2, $param3); } public function createObj2($param1, $param2){ $this->objects[]=new Obj2($param1, $param2); } } ?> Now I want the same functionality but using just the __call(), something like this Code: [Select] <?php class creator{ private $objects = array(); public function __call($name, $args){ $this->objects[]=new $name($param1, $param2); } } ?> So, the main problem is, in the $args variable i get an array with all the args passed, How can I make the call to create a new object when in the object constructor are individual parameters needed and not an array of parameters. Thank you in advance. hey guys i have a __call method in my class...the probelm im having is how to get the arguments into this line Code: [Select] return $this->_db->$method($arguments); if arguments where "test1" and "test2" i want the call to do Code: [Select] return $this->_db->$method("test1", "test2"); the code below will put all arguments into one if anyone can help me on how i can seperate please Code: [Select] public function __call($method, $arguments) { if (method_exists($this->_db, $method)) { $arguments = implode(', ', $arguments); return $this->_db->$method($arguments); } } I am using a script to take postcodes and give distances between them and list all postcodes within a radius. Where it should list all the postcodes in the radius it provides and empty array - any clues?? the table is 'geodb' relevant fields are postcode place latitude longitude and the code is Code: [Select] if(isset($_GET['Search'])) { $postcode = strtoupper($_GET['postcode']); $radius = $_GET['radius']; echo $postcode . '<br>'; echo $radius .

The for has ALOT of imputs and can also generate new one automaticly using javascript. My problem is that come of them returns empty arrays while other works. Is there a maximum or some kind that a form can submit at the time? i made a print_r on the $_POST var and this is what i got (I tooke out all the other arrays but theres a lot more then what i am posting) [...] print ('<tr> <td> <input type="text" size="9" name="styleenc[]" value=""> </td> <td> <input type="text" size="9" name="couleurenc[]" value=""> </td> <td> <input type="text" size="2" name="c_y[]" value=""> </td> <td> <input type="text" size="2" name="c_a_s[]" value=""> </td> <td> <input type="text" size="2" name="c_a_l[]" value=""> </td> <td> <input type="text" size="2" name="c_a_o_s[]" value=""> </td> <td> <input type="text" size="9" name="descenc[]" value=""> <input type="hidden" size="9" name="invisible3[]" value="3"> </td> </tr>'); [...] Code: [Select] Array ( [styleenc] => Array ( [0] => [1] => [2] => [3] => [4] => ) [couleurenc] => Array ( [0] => [1] => [2] => [3] => [4] => ) [c_y] => Array ( [0] => [1] => [2] => [3] => [4] => ) [c_a_s] => Array ( [0] => [1] => [2] => [3] => [4] => ) [c_a_l] => Array ( [0] => [1] => [2] => [3] => [4] => ) [c_a_o_s] => Array ( [0] => [1] => [2] => [3] => [4] => ) [descenc] => Array ( [0] => [1] => [2] => [3] => [4] => ) [invisible3] => Array ( [0] => 3 [1] => 3 [2] => 3 [3] => 3 [4] => 3 ) [emplacement] => sdcwedf ) They should all have values i don't get it ... the only one that has values is invisible3 that has been manualy specified with value="3" I have the form / script below that works to add multiple rows of data with one query. One thing I did not think about is what if the first set of form fields are filled and the second is not. Currently the script insert an empty row. I'm sure how I would go about checking for an empty row and if there is an empty row ignore it and do not put it in the DB. Can someone point me in the right direction? Code: [Select] <?php // Begin the script for this page if (isset($_POST['submit'])) { //Assign each array to a variable $id = $_POST['id']; $store = $_POST['store']; $item = $_POST['item']; $itemprice = $_POST['itemprice'];

The query is coming back as an array. Typically, each product image array looks like this: $d = SimpleXMLElement Object ( http:// => [url]http://ecx.images-amazon.com/images/I/51aUIul6XjL._SL160_.jpg [Height] => 160 [Width] => 112 ) The code goes like this: Code: [Select] if ($d=$E->MediumImage) { $iu=$d->URL; $ih=$d->Height; $iw=$d->Width; echo count($d); if (strlen($iu) > 0) {echo "<center><a href='$url' target='_blank'><img src='images/amazon_noimage.jpg' width='175' height='175' border='0'></a></center>";} else {echo "<center><a href='$url' target='_blank'><img src='$iu' width='$iw' height='$ih' border='0'></a></center>";} } However, images/amazon_noimage.jpg never shows up (even though it is linked correctly, as I've tested this link). I have tried the following: if (strlen($iu) > 0) if (count($iu) > 0) if (strlen($d->URL) > 0) if (count($d->URL) > 0) if (isset($d)) if (!isset($d)) etc ... If I display the following, where there is no image, I get nothing displayed: echo $iu; print_r($iu); echo $d->URL; etc ... However, if there is an image, I get a link, such as the following: http://ecx.images-amazon.com/images/I/51c2BFpDN0L._SL160_.jpg There seems to be NOTHING that I can do to trigger the 'ELSE' part of the if statement. This is a total enigma to me ... any ideas?? What I am trying to do is to submit as POST values to database_write.php, from within the while statement. What is happening is I am getting the second row of data every time I change the primary button.
Currently database_write.php is just doing print_r($_POST), And my array is always the same, no matter which select box I choose from. How can I get the values to be associated with the row I am currently changing? Any help would be great, thanks.

Hi
How can limit only required input fields cannot be empty.
<form name="test" method="post" action="test.php"> <label for="quest"> <input type="text" name="quest" /> <!-- REQUIRED --> </label> <label for="answers"> <input type="text" name="answers[]" /> <!-- REQUIRED --> </label> <label for="answers"> <input type="text" name="answers[]" /> <!-- REQUIRED --> </label> <label for="answers"> <input type="text" name="answers[]" /> </label> <label for="answers"> <input type="text" name="answers[]" /> </label> <label for="answers"> <input type="text" name="answers[]" /> </label> <label for="submit"> <input type="submit" name="submit" value="Submit" /> </label> </form>Following function working only on all empty input fields, i need help to enable button when required fields is not empty.
$(document).ready(function() {
var $submit = $("input[type=submit]"),
$inputs = $('input[name=quest], input[name=answers[]]');
function checkEmpty() {
// filter over the empty inputs
return $inputs.filter(function() {
return !$.trim(this.value);
}).length === 0;
}
$inputs.on('keyup', function() {
$submit.prop("disabled", !checkEmpty());
}).keyup(); // trigger an initial blur
});
Hi I am looking to be able to pass an array to mysql_fetch_row() not sure where i am going wrong. works fine like this. Code: [Select] mysql_select_db($DB_NAME); $new = mysql_query("SELECT * FROM {$DB_TABLE}"); if (!$new) { echo 'MySQL Error: ' . mysql_error(); exit; } $row = mysql_fetch_array($new); while ($row = mysql_fetch_array($new)) { echo $row['username'] . $DELIMITER . $row['firstname'] . $DELIMITER . $row['lastname'] . $DELIMITER . $row['password'] . $DELIMITER. "example@gmail.com" . $DELIMITER . "author"; echo "<br />"; } But really need too be able to do it this way. Code: [Select] mysql_select_db($DB_NAME); $new = mysql_query("SELECT * FROM {$DB_TABLE}"); if (!$new) { echo 'MySQL Error: ' . mysql_error(); exit; } $row = mysql_fetch_array($new); echo "<pre>"; //print_r($row); echo "</pre>"; $sam = array('username','firstname','lastname'); while ($row = mysql_fetch_row($new)) { echo $row[$sam] . $DELIMITER; echo "<br />"; } So it will just loop through the array so i can keep adding to it by just adding an extra parameter to the array. Any Help Stuck???? Hi all ! What would be the best way to identify and handle an empty array sent from JS to PHP? This rather simple looking problem has resulted in a lot of confusion to me. $_POST['myArray'] = ""; // an empty string -- this is how the empty array from JS is received in PHP
Hi, i'm new here and hope i've finally found a forum where i can find the perfect solution for my questions.
Well since a year now i started to work with PHP and still now and then there are some things where i seize on. My question is on of those situations.
I have the following code:
if (isset($_POST)){
foreach ($_POST as $key => $value){
if (!empty($value)){
$update_rma_detail_stmt = $dbh->prepare("UPDATE rma_detail SET $key = ? WHERE rd_rma_nr = ?");
$update_rma_detail_stmt->bindParam(1, $value);
$update_rma_detail_stmt->bindParam(2, $getadmrmaid);
$update_rma_detail_stmt->execute();
}
}
}
All i want is when there is an empty (not filled in) input field because it is not mandatory the foreach still continuous to the end.
When i use
if (!empty($value)){
It still outputs these error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 1366 Incorrect integer value: ' '
However, when i dont use i got an other error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22007]: Invalid datetime format: 1292 Incorrect date value: ''
It is however so that the datetime is the very first empty field it come across when looping. I think my if (!empty($value)){ is doing the right thing but still gives error's on integers. Can it be? I allready tried to use trim() or array_filter() but because i previously never used it i dont know if i am doing it the right way so any help is welkom!
Thanks!

Hi fellow developers, I'm having a real problem at the moment, I'm trying to capture everything in between <body></body> tags using the following code but it does not print anything: $lines = file("http://www.bbc.co.uk/"); foreach ($lines as $line_num => $line) { $thecontent .= htmlspecialchars($line) . "<br />\n"; } preg_match('/<body.*?>(.*?)<\/body >/', $thecontent, $htmltext); $moretext = $htmltext[1]; echo $moretext; When you do place a "print($thecontent);" into the code the entire html for [whatever the website] does display but I want to capture only the html code in between the body tags. I've tried everything but I just can't get this to work. I would appreciate anyone's help and I'd like to thank you in advance. M |
