PHP - Passing Arguments Into Another Function

Passing Arguments Into Another Function	View Content

I have a odd one here, two classes and one which calls another class.
I want to pass all of the parameters from the array as seperate variables into the next function. Hope my example explains a little better

class master{ public function __call($name, $args) { second->$name($args); }}class second{ public function example($param1, $param2) { }}master->example($param1, $param2);()

( i know its not accurate php, but should get the idea of what im trying to do)
I need to do something with the following line
second->$name($args);
Where param1 and param2 will be seperated out
Is there a php function which you can tell it the class, method name and pass it an array of parameters?

Thanks

Hi,

I am trying to display a variable that is supposedly created in a different page. Here is the code. But it is not displaying in the next page:

ADMIN_login.PHP - Page URL

<form name="form2" action="admin_login_success.php" method="post">
<?php
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name="test"; // Database name
$tbl_name="masterschoolinfo"; // Table name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

// username and password sent from form
$myusername=$_POST['adminusername'];
$mypassword=$_POST['adminpassword'];

// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);

$sql="SELECT * FROM $tbl_name WHERE school_username='$myusername' and school_password='$mypassword'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:Admin_login_success.php");
}
else {
header( 'Location: Adminportal.PHP' ) ;
}
?>
</form>

admin_login_success.php - Next page where the variable is to be displayed based on the username provided in the above page:

<html><body>
<?php
include 'mysql-connect.php';

$schoolID=mysql_query("select SCHOOLID from masterschoolinfo WHERE school_username='$myusername' and school_password='$mypassword'") or die(mysql_error());
while($row = mysql_fetch_array( $schoolID )) {

// Print out the contents of each row into a table
echo "<tr><td>";
echo $row['SCHOOLID'];
echo "</td></tr>";
}

Global Variables And Function Arguments?

Similar Tutorials

Hello

I've have read that global variables should not be used.

so if i have 2 .php files:

index.php - main content php file

sitefunctions.php - php functions site file

on my index.php page i have the following (an example of my problem):

<?php

displayError($errorID);

?>

and in the sitefunctions.php file i have the following (an example of my problem):

<?php

function displayError($errorID)
{
        if($errorID == 1)
        {
              echo "Password Failure";
        }
        else
        {
              echo "Other Failure";
        }
}

?>

now that works but since when first accesing that page the $errorID is not set then i get an error. How can i achieve this without first setting a blank $errorID global variable?

Thanks

Trying To Pass Arguments Into Function (one Arg Is Missing)

I 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

   $total_shipping = 0;

   // Calculations per product with returned sum sent outside to $grand_total variable
   $total_price += $price;
   $total_tax += $tax * $price;
   $total_shipping += $shipping * $price;
   $sub_total = ($total_price + $total_tax + $total_shipping); # This calculates the sub-total (or Grand total) for each product
   echo "<li>".$product.": $".$price."<br />";         # THE PRODUCT NAME & PRICE SHOULD DISPLAY HERE (NAME IS NOT SHOWING WHICH IS PROBLEM)
   # I had echo statement to confirm calculation on product was correct
   # echo "Grand Total is $".$sub_total."<br />";
   return $sub_total; # This breaks out of the function when Candle Holder IF statement is true; returning value

No Warnings Displayed If I Reference Arguments At Call Time For A Function

Hello,

I was trying out some code to check out how some of the php settings work and when i tried allow_call_time_pass_reference to see if it works, it doesn't spew out any warning or error like the comments in the .ini file mention (or in the manual sites). Maybe i'm not using some other setting in order to see this? Here is my EXACT code.

<?php
ini_set('display_errors',1);
error_reporting(-1);

$variable = 'String';

function display($variable) {
return $variable;
}

echo display(&$variable);

Outputs : String. No errors, no warnings.

Passing Class To Function

Mon Aug 24, 2020 2:41 pm

I'm using php_serial.class.php, called once

require_once("php_serial.class.php");

and call it $serial:

$serial = new phpSerial;

The above are in a global.php file that sets up the serial com parameters.

In another file, I include global.php that contains my other code to send and read from the class

In a function, I pass the class:

Function checkInput($serial){

And one in the Function:

$read = $serial->readPort();

This throws an error: "PHP Fatal error: Uncaught Error: Call to a member function readPort() on string"

If I do the $read outside of the Function, it doesn't throw the error so I assume I'm doing something wrong passing the class to the function?

Passing String Through A Function Using Return

Hello everyone,

Pretty much what I am trying to do is run a query and based of the queries result, return a string - as of now it is turning up blank and cant seem to pass any strings through the function.

Current function:

function addNewBookmark($hash,$url,$title,$username){

Code: [Select]
$query = "INSERT INTO bookmarks (hash,url,title,username) VALUES '".md5($hash)."', '".$url."', '".$title."', '".$username."')";
$result = mysql_query(query, $this->connection);
$message = '';
if(mysql_affected_rows($this->connection)!=1) {

$message = 'This URL already exists in the database!';
return $message;
}
else
$message = 'The URL was shared!';
return $message;

}
The above code seems to run fine, just cant seem to pass a string...read that you can possibly use a __toString function? but that keeps throwing errors when I try to work with it.

Thanks all!

Been stumbling my way through OOP and seem to be understanding it for the most part (I think..) But I've got a couple questions / kinks that I can't seem to work out.

a) How do I return a variable from a class so that a different class has access to it (meta_data)
b) I'm getting a "$this" cannot be redefined error (which I know why, but I don't know how to fix))
c) How do I call a function from within one class, where the function resides in another class, AND pass it variables?

Any help would be greatly appreciated

I've tried to Google warrior A and I think I can figure that one out, but B and C are proving to be the real stumbling blocks.

Firstly i am new to php.Iv currently got this while loop iterating through a database drawing polygons from the info in the datatable.each polygon has its own id stored in the datatable and with the on click event i am trying to just output to the screen the specific id of the polygon clicked on.It looks ok to me but it doesnt work for some reason. Below is the loop and the function it is trying to call.
///////////////////////////////////////////////////////////////////////
<?php
while($info = mysql_fetch_array( $data )){
echo "<polygon fill=".$info['fill_colour']." stroke=\"black\" id=".$info['id']." onclick=\"buildingClick(id)\" points=".$info['coordinates']." />";


}
?>
///////////THIS IS THE FUNCTION///////////////////////////
<?php
    function buildingClick($id) {

    echo "building id : {$id}";

}
?>
///////////////////////////////////////////////////////////////////

If anyone could help it would be hugely appreciated.
