PHP - Passing Parameters As Variables Vs Passing Parameters As An Array

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?

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&param2=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!

Code: [Select]
<?php 
$parentesco .=' 

<ul><li><a href="children.php?category_id='.$idc.'&name= '. $name2 . '">'. $name. ' </a></li></ul>'; ?>
in the url string $idc is passing but $name2 is not. $name2 is pickup from a query, I echo that value everywhere in the code and it echo its value but is not passing so how.

Help

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;
//etc

When 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?

Hello all,

I'm hoping someone can help me out. Here is the code I have for a page that contains a user form:


<?php
include "include/dbc.php";

include "include/header.inc";
?>

<style type="text/css">
.mydate{
color:#00F;
text-decoration:underline;
cursor:pointer;
}
</style>

<script type="text/javascript">
function displayDate(d){
var date=new Date();
var D=date.getDate();
date.setDate(D+d);
var YYYY=date.getFullYear();
var MM=date.getMonth()+1;
MM<10?MM='0'+MM:null;
var DD=date.getDate();
DD<10?DD='0'+DD:null;
var span=document.getElementById('date');
span.innerHTML= 'Entries for '+MM+'/'+DD+'/'+YYYY;
}
onload=function(){displayDate(0)};
</script>

<h1>Food Diary</h1>

And here is the page that the user information is supposed to be passed to:


<?php
include "include/dbc.php";
include "include/header.inc";
$duration = $_POST["duration['.$row['Name'].']"];
echo '<h1>Added Activities</h1>';
echo $duration;
?>


Well, this isn't working for me. The second page code returns this error:


Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING


When I execute print_r, the values are returned to me. So I have two questions:

1) What do I need to do to change the code on the 2nd page to echo and POST the array?

2)The database contains multiple exercises under the same name. So, when the variables are passed to the 2nd page. All the values are returned regardless of whether they have been filled out or not. What can be done to only returned the user input and not the blank variables?
