PHP - Getting Any Variables Passed In A Url String

I have a string that looks like /index.php?g1=111&g2=222&g3=333.  How can I obtain the value of g1 (i.e. 111)?  It does not represent the current state of the server thus I cannot just use $_GET.  It also is not necessarily the first item.

The script below appears to work, however, http://php.net/manua...n.parse-url.php states
  This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards compatibility requirements it makes an exception for the file:// scheme where triple slashes (file:///...) are allowed. For any other scheme this is invalid.  
It appears that my string is a URI and not a URL, but I might be wrong.

How should this be accomplished

<?php
$str='/index.php?g1=111&g2=222&g3=333';

$array=parse_url($str);
parse_str($array['query'],$get);
echo("<p>{$get['g1']}</p>");
?>

I have the following code which has deliimiters of |||| and I need to break it apart into three strings and have a variable assigned to each string.

I've tried exploding it but won't dynamically increase the variable.  I know at one point about a year ago I used something like $var.=$foo and the $var would increase $var1, $var2, etc...

Here's the string I need to break.j (And the string will be different every time, and some will have 2 string delimited  some will have 20, and some inbetween.

hello, im wondering how to properly code the following.

Code: [Select]
$stdate = date( 'Ymd', strtotime($pdate) );
$sttime = date( 'His', strtotime($tstart1) );

$dtStart = ".$stdate.'T'.$sttime.'Z'";

echo "$dtStart";

i would like the echo to read 20110309T050000Z

Pretty simple I would think but I'm unsure on the syntax. I have a variable, $ename. It's actually data from a form that I pass to said variable. What I want is to then in turn use this string in a mkdir() function. Something like

Code: [Select]
mkdir("dir/folder/$ename/");
Obviously that doesn't work. I'd imagine I have to use some sort of . syntax.

I need to echo out some string variables in a form. I also want to add some validation for Name, email etc. I think I have the code right or close, but I can an error on the index.php page which is.
"Fatal error:  Call to undefined function  form_row_class() in index.php on line 14"

here is the code for the form

Hi Guys and Girls,

Long time lurker, first time poster!

I am usually able to read through the forums and find and answer without having to start a new thread but I've tried my best to no avail.

I am having trouble with the following code:
$afname="Gareth";
$alname="B";
$awayoption.="<OPTION VALUE=\"".$afname." \"".$alname."\">".$afname."&nbsp;".$alname;

I would want that to produce the following:

Code: [Select]
<OPTION VALUE=Gareth B">Gareth B
The actual result at the moment is:

Code: [Select]
<OPTION VALUE="Gareth "B">Gareth&nbsp;B
It has an extra " in the middle. Any ides or help would be great!

Cheers

Code: [Select]
$query  = "SELECT content FROM license WHERE serial  = '".$serial."'";

I have an audit trail that record users ids and a copy of the sql string for any updates they make to my application. This is very easy for me to follow to  find exactly where changes happened but do end users it is a bit of a challenge.

Has anyone seen or made a script that can either compare two sql strings to see what fields have different values or a script that takes an SQL string and outputs its field names and values to an array that I can use for comparisons?

Example being the look at a update made by user X, the database pulls the sql for that change then looks for the previous change up any user before (update sql should have a value for all fields) then compares to see what user X changed.

If not im thinking of case statement to divide sql request between inserts and update then writing a script to split the strings based on where the commas were.

Any thoughts?

Hello! I want to be able to make a code that tells me how many saturdays have passed till today. I've tried a couple of things but nothing. Any help?! Thanks!

 

Hi All,

I've been trying to access xml data from an API feed, but it needs a Variable to be passed to an include file without a form. the include is at the header of the page.

in the code below, i'm trying to retrieve the variable $project_add from the $xml_2 feed. $proj_add_ID comes from another feed and is being passed ok. 

foreach ($projects_1 as $proj_1) {

                        $job_no =$proj_1['job_no'];
                        $job_name =$proj_1['job_name'];
                        $job_status =$proj_1['job_status'];
                        $job_staff =$proj_1['job_staff'];
                        $job_due =$proj_1['job_due'];
                        $clr_1 = $colors_1[$job_status];
                        
                        if ($err_2) {
                        echo "cURL Error #:" . $err_2;
                         } else {
                        $_POST['job_id']= $job_no;
                        $xml_2=simplexml_load_string($response_2) or die("Error: Cannot create object");
                        $proj_add = $xml_2->xpath("CustomFields/CustomField[ID ='$proj_add_ID']");                         
                            foreach($proj_add as $item_2) {
                            $project_add = "$item_2->Text";
                        }            
                        echo "<div class='row no-gutters'>";

                                . "<input type='hidden' name='est_min' value ='". $jdata['est_min'] ."'>"
                                . "<input class ='form-control bg-white text-dark font-weight-bold' type='date' name='start_date' value='" . date('Y-m-d', strtotime( $jdata['display_date_1'] )) . "' onchange='this.form.submit()'>"

                       }

The include file is like this

/ collect Custom Felds
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // collect value of status input field
    $job_no = $_REQUEST['job_id'];
      } 

if (isset($_POST['job_id'])) {
$job_no = $_POST['job_id'];
}

if (isset($_GET['job_id'])) {
$job_no = $_GET['job_id'];
}

$curl_2 = curl_init();

curl_setopt_array($curl_2, array(
  CURLOPT_URL => "https://api.xxx.com/job.api/get/$job_no/customfield?apiKey=xxx&accountKey=xxx",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "GET",
  CURLOPT_HTTPHEADER => array(
    "Accept: */*",
    "Accept-Encoding: gzip, deflate",
    "Cache-Control: no-cache",
    "Connection: keep-alive",
    "Host: api.xxx.com",
    "Postman-Token: xxx",
    "User-Agent: PostmanRuntime/7.17.1",
    "cache-control: no-cache"
  ),
));

$response_2 = curl_exec($curl_2);
$err_2 = curl_error($curl_2);

curl_close($curl_2);

The problem is the variable $job_no isn't getting passed to CURLOPT_URL so it's not retrieving the data required. i need to be able to retrieve this data without submitting a form as it's in a foreach loop and the Id is specific to each iteration. is there a way to do this? I have been able to achieve this by putting the include within the div tags that it will be displayed but it just slows down everything too much and hangs. 

Any help will be much appreciated. 

Kind regards,

Michael Bennington.

Hi,

I want to update a row when 30sec are passed on a page. If not nothing happens(not updating row).

Example:
You go to example.php>> 30sec pass, update row>> 30sec not over, no update.

it does not necessarily have to be second it can be minutes or hours.
Who can help me?

Hope its clear enough, Thanks.

In my main script I set $errorArray with values when required survey questions go unanswered.

The ne code that checks for missing required values is working perfectly, and right before I pass $errorArray to a function which rebuilds the survey questions - this time with the error messages - I do a var_dump($errorArray) and that array has errors in it as expected.

But while my function that re-builds the survey questions gets called and does indeed re-build the survey questions, the $errorArray isn't getting pased for some strange reason?

(I'm not sure if i have ever passed an array to a function before.)

In my function I have...

	function generateSurveyItem($dbc, $questionNo, $questionID, $surveyResponseArray=NULL, $errorArray=NULL){
	 
	}
	

 

When I var_dump($errorArray) at the top of the function, and submit a blank form, I end up with a blank page and a file path to my PHP script ending with...

	/public_html/utilities/function.php:3010:null
	

 

Questions:

1.) What is happening?

 

2.) I thought =NULL in the parameter list just meant that the argument is "optional"?

 

3.) I am able to successfully pass $surveyResponseArray to this function, so what is up with $errorArray?

 

P.S.  When I run things, and submit an empty form - thus no "required" fields get completed - the survey gets re-displays, and any values chosen are "sticky", but my error messages should also be displayed to let the user know what is mising, and that is the part that isn't working?

This has to be something silly stupid to fix...

Hi

I use Dreamweaver to do a lot of my work on a php/mysql database. I have two tables - applications and contacts and they are linked by the id appid. When I view a page with all of the application and contact details the url contains the appid as a number at the end (eg .../Summary.php?appid=639)
When I want to edit one of the contacts I go to the edit page but this is identified by a contact id so that url looks like:
../EditContact.php?contactid=32
When I update the contact's details I would like to return to the summary page but can't as the url gets muddled between the two different ids so I end up at a page with no info on it.

How can I get round this?

I'm sorry my explanation isn't very clear but any help is much appreciated.

I am trying to pass a php variable to javascript but it's not working. This is the "sketch" of my code.

<?php
$url="asset/go/";
?>

 

<!DOCTYPE html>
<html>
    <head>
        <title>Page Title</title>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

    </head>
    <body>
        <script>
            var user="mayor";
            var url ='<?php echo json_encode($url); ?>';
       if(user=="mayor"){
           alert(url);
       }
        </script>
    </body>
</html>

As it is now, it comes with the output below:

<?php echo json_encode($url); ?>

If I remove the quotation around the php in d jQuery, it throws an error in syntax.

Also both codes are located in the same file named test.php

Thanks in advance.

Good day freaks.  I am pulling my hair out trying to figure this out.  I am trying to pass patterns for preg_replace through $_GET and then apply them.  The object is to highlight certain words in a chunk of text. 

Say I want to highlight bounded cases of 'foo' in the text.  So here's what I'm doing: Code: [Select]
$string = urldecode($_GET['highlight1']);       //  $string contains \\bfoo\\b
$search = preg_replace('/\\\\b/','b',$string);   // $search contains \bfoo\b  as I want it to
$replace = preg_replace('/\\\\b/','',$string);    // $replace contains \foo\  >:-(
$pattern = '/'.$search.'/i';
$text = preg_replace($pattern,'<span style="background-color:yellow;">'.$replace.'</span>',$text);

The problem is that no matter what I try for the pattern for $replace, it winds up with backslashes around foo.  How do I get rid of these?

(I should say that I discovered the pattern/replace for the $search string by experimentation and I don't understand why the pattern doesn't pick off all the backslashes in that case--but at least it does what I want).

TIA

Steve
