PHP - When Passing Parameters, Do I Pass Only What I Need Or Do I Pass Entire Parent Object?
I work with a large codebase and I have this situation come up fairly often:
the legacy class has large objects such as:
$design->motor->dimensions->a; $design->motor->dimensions->bd; $design->specifications->weight; $design->data->height; //etcWhen I create a new class, that class sometimes operates on the specific data, so say:
class MyClass
{
public function compute($weight, $height, $a)
{
//stuff
}
}
//and I call this for example as such:
(new MyClass())->compute($design->specifications->weight, $design->data->height, $design->motor->dimensions->a);
CONS: Potential issue: if design specs change and I need to change things parameters in "compute" function, I need to "re-key" the variables I pass to the function, and adjust things accordinly in MyClass as wel.
PROS: only the exact data is being passed, and this data can come from anywhere it is viable, so in effect the function is fairly well separated, I think.
Alternative option for me is to pass the entire design object, i.e
class MyClass
{
public function compute(&$design) //can also be done via DI through a setter or constructor.
{
print $design->specifications->weight;
print ($design->data->height + $design->motor->dimensions->a);
//stuff
}
}
(new MyClass())->compute($design);
PROS: In this case when things change internally in which variables are needed and how things are computed, I only need to change the code in compute function of the class itself.
CONS: MyClass now needs to be aware of how $design object is constructed.
When it comes to this parameter passing, and Dependency Injection like this in general, does Computer Science advocate a preference on this issue? Do I pass the entire object, or do I pass only the bits and pieces I need?
Similar TutorialsI tried many ways but unable to pass sessions to virtual subdomains on my site.. I edited ihi.ini file and included Code: [Select] session.cookie_domain = .mydomain.com I like to add that session is active on my main domain for www.mydomain.com only.. So how do I pass sessions for WWW to other subdomains ? Thanks n Advance I'm trying to get a simple table to display and am not sure how to make it happen. Table will have just 2 columns. A TIME and an EVENT. What I want to have happen is for the first row to show the TIME and next to that, the EVENT. If a TIME has more than one event going I want the next row to show an empty first cell and then the second event below the first. If I set up the loop the only way I know how (so far) it would also output the TIME value again and again as many times as there were events for that same time. For example what I don't want is: 9:15 Sunday School 9:15 Nursery Available What I do want is: 9:15 Sunday School Nursery Available Thanks. Can someone explain to me how this is done? I have some function or method. Is there a better design patter to implement this?
function myFunction($a=null,$b=null,$c=null,$d=null,$e=null,$f=null,$g=null,$h=null)
{
//Do a bunch of stuff
}
Maybe the second function?
function myNewFunction($data=array())
{
$data=array_merge(array('a'=>null,'b'=>null,'c'=>null,'d'=>null,'e'=>null,'f'=>null,'g'=>null,'h'=>null),$array);
//Do a bunch of stuff
}
Please provide decision making factors why you would use one approach over the other.
hello how do i pass a foreach loop through "Passing by Reference" say i have a foreach loop in a function like this: Code: [Select] function findText(&$output){ $word = Text::find_all(); foreach ($word as $words){ $output = $words->text; } } then one the page i put Code: [Select] findText($output); echo $output; that will just give me the last word in the database. so how do i get it to echo out the array on the page ? thanks I am calling CURL and trying to do a POST request with parameters: Code: [Select] $curl = curl_init(); curl_setopt($curl, CURLOPT_HTTPHEADER, Array("Accept: application/json", "Content-Type: application/json")); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 15); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true); curl_setopt($curl, CURLOPT_USERAGENT, "curl 7.23.1 (x86_64-unknown-linux-gnu)"); curl_setopt($curl, CURLOPT_USERPWD, "username:password"); curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($curl, CURLOPT_URL, "https://www.mydomain.com/route"); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, "key1=blah1&key2=blah2"); return curl_exec(curl); The problem, inside the request at http://www.mydomain.com/route I am not seeing any POST parameters passed. I.E. Code: [Select] print_r($_POST); Code: [Select] Array ( ) Should have key1=blah1 and key2=blah2. Any ideas? When i pass entire url in a get variable as http://www.example.com/index.php?url=http://www.yahoo.com/ I am getting the following error Forbidden You don't have permission to access /index.php on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. But there is no problem when i use the following http://www.example.com/index.php?url=www.yahoo.com/ http://www.example.com/index.php?url=yahoo.com/ http://www.example.com/index.php?url=yahoo&value=1 I am getting "Forbidden-error" only when i include "http://"(even if it is urlencoded) in get variables. Can any one help me... Code: [Select] $col = 0; if ($num_products_count > 0) { while (!$specials_index->EOF) { $list_box_contents[$row][$col] = array('params' =>'<a href="#">' .zen_image(..). '</a>'), $col ++; } } now i want to pass some values<img src="1.jpg">,<img src="1.jpg">,<img src="2.jpg">,<img src="3.jpg">,<img src="4.jpg">,<img src="5.jpg"> to zen_image(..). how should i do? namely, if there are five loops.i want to change zen_image(..) output result to (<img src="1.jpg">,<img src="1.jpg">,<img src="2.jpg">,<img src="3.jpg">,<img src="4.jpg">,<img src="5.jpg">) Hello again, Though this question is somewhat related to my prior note, I thought it was probably different enough to justify a separate topic... So, I have a link at site1.com/dir/admin/?param1=value¶m2=value, etc, which I want to redirect to site2.com with all the rest being the same. Thanks to your help, it's working with two specified parameters However, there is a relatively short list of potential parameters (maybe 5?) but not all of them are passed in all calls to the link. In other words, sometimes the link is called with param1 and param2, sometimes with 1 and 3, sometimes with 1,2, and 4, etc. What is the best way to do the redirect which would ensure that all the parameters which are sent to the initial link are then included in the redirect? Is there a way to search the incoming link and grab all parameters in it? Or do I put together the list of possible parameters and then grab the values with $_GET for all of them and then pass all of them even if the values are null (not sure whether the app will accept that or not...) I hope I'm stating the question clearly enough! Thanks in advance for your help! I just signed up for an affiliate network (commission junction) to help me drive traffic to my donation generation website for Charities. My Software uses CAKE PHP on an Apache Server with MySql. I had to put a pixel on the order confirmation page passing the Transaction ID and The Purchase Amount from the database. The Transactions are located in the transaction table but the code that was written is passing EVERY Transaction in the database every time something is purchased. The Columns for the transaction table are ID CREATED MODIFIED USERID CLASS TRANSACTION_TYPE_ID and AMOUNT I have 32 types of Transactions in my Transaction_Type Table, the only transaction_types that are sales generated by the affiliate network are transaction_type 2. The code I have now which isn't working correctly is. <?php // Make a MySQL Connection mysql_connect("localhost", "frankgth", "andrew2011!") or die(mysql_error()); mysql_select_db("frankgth_groupon5") or die(mysql_error()); // Get all the data from the "example" table $result = mysql_query("SELECT * FROM `transactions` ") or die(mysql_error()); // keeps getting the next row until there are no more to get - while($row = mysql_fetch_array( $result )) { ?> <img src="https://www.emjcd.com/u?CID=1521593&OID=<?php echo $row['id'];?>&TYPE=349217&ITEM1=PURCHASE&AMT1=<?php echo $row['amount'];?>&QTY1=1&CURRENCY=USD&METHOD=IMG" height="1" width="20"> <?php } ?> How Do I only show this pixel if the action is Transaction_Type_ID is equal to number 2,with the Amount and Transaction ID. Thanks in advaced. This site helps charity so i really want to get it working! I'd like to pass a value from a URL to an iframe. This would look as follows: URL: http://www.mysite.com?www.mysite2.com The value (www.mysite2.com) will be an actual web address which should then be inserted into an iframe on www.mysite.com via php. Since I know little to no php, I don't know how the URL has to be structured and what php coding I need to use to include the web address in the iframe. Any suggestions are highly appreciated hello how do i pass a value from 1 function to another i want to use this part Code: [Select] //send the list order to the navigation or list page $PHL = PhLists::by_listNo($PHGlno); foreach ($PHL as $PHLs){ $PHLlno = $PHLs->phList_No; $PHLorb = $PHLs->orderBy; $PHLord = $PHLs->orderDir; } from this very long function.

I have 2 questions:
1) Look he http://www.hellastra...ooking/taxi.php
I have a form and i want to pass values from URL to fields.
So, for example to pass a value to Prefered driver ID field you write this:
http://www.hellastra...?drivercode-123 and the value 123 is passed to that field. I did this with this code:
<?php $sDriverCode = $_REQUEST['drivercode']; ?> <input style="width:100px;" name="drivercode" id="drivercode" value="<?=$sDriverCode?>" data-mini="true" />At the same form i have some radio-type fields. Its the one you see at Type of Vehicle (Standard, Premium etc). When i try to do the same, i cannot get this to work. What i am trying to do is this: Hi guys, I need your help, I have got a problem with the if statement.

Or can i run a javascript function once a query string is passed in the url
Please advice.
