PHP - What Can I Use To Post Values To My Php Script?

Hi

I have a form that is to input data from input fields to a table.
The form is as follows:

                            $query = $DB->query("SELECT country_code, country_id, IF(country_code = '".$country_code."', '', '') AS sel FROM exp_sme_countries WHERE site_id='".$this->settings['site_id']."' ORDER BY country_name ASC");
                            foreach ($query->result as $row)
                            {
                               $options .= '<label>' . 'Phrase for ' . $this->settings['countries'][$row['country_code']] . '</label>' . '<br />';
                               $options .= '<input style="width: 100%; height: 5%;" id="country_data" type="text"  name="country_id[]"  />' . '<br /><br />';
                               $options .= '<input type="hidden"  name="country_data[' . $row['country_id'] . ']" value="'.$row['country_id'].'"  />';
                            }


This outputs:
Code: [Select]
<input style="width: 100%; height: 5%;" id="country_data" type="text"  name="country_id[]"  />
<input type="hidden"  name="country_data[68]" value="68"  />

<input style="width: 100%; height: 5%;" id="country_data" type="text"  name="country_id[]"  />
<input type="hidden"  name="country_data[28]" value="28"  />

What I need to do, is get the values from the input fields and then match them with the correct hidden field value

So if in the first input field, I typed in 'Test data' and the second input, i typed 'This is great'

On the POST, I need to find the the value ('Test data') and also the value from the hidden field.

So something like:
Quote

The text you entered is: Test data with hidden value of 68
The text you entered is: This is great with hidden value of 28


I'd rather not use $_GET as this is a form that inserts data into a database.

Could someone point my in the right direction or provide an example?

I am having trouble with passing values with a POST to another php file.  I am getting the error :  undefined index : productID and undefined index: filename.  I have also tried :  <form   method = \"POST?pdib=$processID&filename=$filename\" action = \"upload2.php\"  >  When I look at the array of superglobals, they are both defined.  Thank you! 

 Here is the code :

drawfirsttwoforms:

$sql = "SELECT ProductFilename, ProductName, ProductID, ProductDescription,ProductCost,ProductQuantity, ProductCatTitle FROM products 
INNER JOIN customers ON customers.CustomerID = products.CustomerID 
WHERE ((products.ProductKeyWord1 = ?) 
OR (products.ProductKeyWord2 = ?) OR (products.ProductKeyWord3 = ? ))  AND (products.ProductCatTitle = ?) ";

$stmt = $dbo->prepare($sql);
$stmt->bindParam(1, $keyword1);
$stmt->bindParam(2, $keyword1);
$stmt->bindParam(3, $keyword1);
$stmt->bindParam(4, $titleOfSelectedDropDown);

$stmt->execute();

while ($row = $stmt->fetch()) {

//these variables do have values here
$productID = $row['ProductID'];
$filename = $row['ProductFilename'];

$string1 .=  "  
<div  class = \"A\" id = \"$mainDiv\">
<p id = \"link1\">product id   :$productID</p>
<p>category id  :$category</p>
<div class = \"A\" id = \"endz\"></div>
<div class = \"A\" id = \"startz\"></div>
<div class=\"container\">
<div id = \"testing\" >testing <div>
<div id = \"$displayID\" >  </div>
<div class=\"row\" >
<div class=\"col\">
	
	<form   method = \"POST\" action = \"upload2.php\"  >
      
      
    
	<input type=hidden id='$productID' name= '$productID' value=\"A\">
	<input type=hidden id=\"$filename\" name=$filename value=\"B\">
	
      
      
      <button value = \"Submit\" type = \"submit\"  >submit it</button>
	</form>
	<iframe id=\"upload_target\" name=\"upload_target\"  style=\"width:0;height:0;border:0px solid #fff;\"></iframe> 
	<img width=\"120\" height =\"120\"  id = \"$imageID\"  src=\"../php proj/uploads/$filename?<?php echo filemtime($filename)?>\">
	<button    onclick = \"imageRefresh( '{$filename}', '{$imageID}', '{$_SESSION["msg"]}' )\" >Display</button>
	</div>


AFTER:
  

if (!isset($myObj) && isset($string1))
{
$myObj = new stdClass();
$myObj->htmlstuff = $string1;


//Encode the data as a JSON string
$jsonStr = json_encode($myObj);
echo $jsonStr;
}

 

function printHTML1(keyword){ 
	
	
	const element = document.getElementById("dropDown1");
		
	//const checkValue = element.options[element.selectedIndex].value;
	const checkText = element.options[element.selectedIndex].text;
	
	var val1 = checkText;

	var xmlhttp = new XMLHttpRequest();
	
	
	var keyword1 = keyword;
	var url = "drawfirsttwoforms.php?keyword=" + keyword.value + "&" + "val1=" + val1;
	


	xmlhttp.onreadystatechange = function() {
		
	if (this.readyState == 4 && this.status == 200) {
		
		
		var jsonData = JSON.parse(this.responseText);
		var answerHtml = jsonData.htmlstuff;
		document.getElementById("codehere").innerHTML = answerHtml;

		createAndModifyDivs();


		}
	};
	
	xmlhttp.open("GET", url , true);
	
	xmlhttp.send();
	
	
}

 

upload2.php


<?php
session_start();
$productID = $_POST['productID'];
$filename = $_POST['filename'];

 

When i click my submit button i am posting the following.

		Array
(
    [submitStaffOrder] => 
    [staffMember] => Array
        (
            [0] => 2
            [1] => ANYCHEF1
        )

    [date] => Array
        (
            [0] => 2020-02-18
            [1] => 2020-02-18
        )

    [startTime] => Array
        (
            [0] => 11:01
            [1] => 10:10
        )

    [finishTime] => Array
        (
            [0] => 11:01
            [1] => 10:01
        )

    [delExisting] => Array
        (
            [0] => 
            [1] => toDel
        )

)

I would like to update/insert if delExisting is blank and delete if it has toDel in there.

I have the following but i am pretty sure the if is not working.

$date = $_POST['date'];
	$stime = $_POST['startTime'];
	$ftime = $_POST['finishTime'];
	$del = $_POST['delExisting'];
	$staff = $_POST['staffMember'];

$stmt = $conn -> prepare("
	                         INSERT IGNORE INTO ssm_staff_order (job_id, staff_id, staff_start_time, staff_finish_time, staff_start_date, staff_finish_date) 
	                         VALUES (?,?,?,?,?,?)
	                         ON DUPLICATE KEY 
	                         UPDATE 
	                         staff_start_time = VALUES(staff_start_time),
	                         staff_finish_time = VALUES(staff_finish_time);
	                         ");

	$delstmt = $conn -> prepare("
		                         DELETE FROM ssm_staff_order
		                         WHERE staff_id = ?
		                         AND job_id = ?
		                         AND staff_start_date = ?
		                         ");

	foreach ($staff as $key => $staffId) {
		if ($del == '') {
			$start = $date[$key].' '.$stime[$key];
			$finish = $date[$key].' '.$ftime[$key];
			$stmt -> bind_param('isssss', $jid, $staffId, $start, $finish, $date[$key], $date[$key]);
			$stmt -> execute();
		}
		

		
		if ($del == 'toDel') {
			$delstmt -> bind_param('sis', $staffId, $jid, $date[$key]);
			$delstmt -> execute();
		}
	}
	
}

Can i do what i am trying to do or am i way off here?

 

I struggle with arrays

Edited February 24, 2020 by Adamhumbug

I'm using the following script: http://jsfiddle.net/VzVy6/8/

It give a alert message that slide in/out when a required field is still empty on submit.
The script works fine, and in this example its only one field.

When the field is empty I see the fade in alert message, and when the field has been filled in I see a normal popup alert message:  alert("Would be submitting form");

I can't get it to work to change this alert message to a page POST submit. I was looking online, and I see Ajax examples that I don't get to work.

What I want is that when all fields are filled in, that the form POST submit to another page including the values in the textboxes ofcourse.

Maybe its something really easy, but I have already a headache because tried to get it to work for more then 5 hours in a row.

Thank you for your time.

It's been a while since I've needed to whip anything substantial up from scratch, so my scripting is a little (lot) fast and loose (weird/inefficient) here.

I'm trying to mock up a script that's essentially a quiz/survey. There are a handful of topics, each with a few screens of yes/no questions. At the end, it returns a list of recommendations based on the answers gathered.

The script is posting back to itself. Using print_r ($_SESSION), it seems like all of the post values for the first screen of questions are being assigned to the session array as expected. When the second screen of questions is answered, their values are assigned as well, but the values for the first set go away completely. This continues through subsequent screens, with the values from the previous screen present and all others before missing.

I'd really appreciate a look at my code to see if you tell me the cause or error(s).

Thanks!

Hi all,
Since twitter changed the way they allow people to post, my simple php script to grab the $_POST data from an input and post it to my twitter profile has broken.

I've been reading up on Oauth, but none of the documentation is clear at all. It's quite complex, in fact - they assume you are creating a full app, which I am not - I just want to flick some text to twitter.

I just want to pass a simple string variable to my account - can anyone help me with how to do this?

All help appreciated.

I have a page, that upon post, does some logic, this logic can take 1-30 minutes...
Now sometimes I will get a "Page time out"....and others i wont... even if im requesting the same data.

I used it successfully everytime on my stock xp, with ie8
But cant get it to work on my VISTA WIN7 x64 machins, and another xp machine, after about 1-5 min it says "page time out", then i test it on my stock xp machine, and it can run for 45 min, or runs until everything is finsihed and shows the page.

Any ideas?

Its just keep saying error on line 1
if($_POST["pass"] == $_POST["repass"]){
arepasssame = $_POST[pass];
}

I am working on a website where I have comments posted by users. I want to display 25 comments and if there are more, it will show a linke Older Posts similar to Facebook. Once I click on that, it will list down the next 25 comments and so on. This is something we can see in Facebook. Do you have any idea where I can find this script. I did search on google but couldn't find it. Probably bad keyword selection.

any ideas for the resource.

Thanks,

Faisal

I have a problem about Blog Post Categorization  Script. Can anyone review it ? Instead of showing how much posts that category have it just repeats.

Code: [Select]
<?
$sqlCategories = "SELECT * FROM blog_entry, categories where blog_entry.CategoryID=categories.CategoryID and blog_entry.UserID=".$_REQUEST['UserID']." order by Category asc";
$resultCategories = mysql_query($sqlCategories, $conn);
if (@mysql_num_rows($resultCategories)!=0){
$strcategory="";
while($row_categories = @mysql_fetch_array($resultCategories))
{
$categoryduplicate=0;
$arrcat = explode(",",$strcategory);
for($i=0;$i<strlen($arrcat);$i++)
{
if($arrcat[$i]==$row_categories['CategoryID'])
{
$categoryduplicate=1;
}
}
if($categoryduplicate==0)
{
if($strcategory=="")
{
$strcategory=$row_categories['CategoryID'];
}
else
{
$strcategory=$strcategory.",".$row_categories['CategoryID'];
}
$sqlCategories2 = "SELECT * FROM blog_entry where CategoryID=".$row_categories['CategoryID']." and UserID=".$_REQUEST['UserID'];
$resultCategories2 = mysql_query($sqlCategories2, $conn);
if($row_categories['CategoryID'] == $_REQUEST['CategoryID'])
{
echo "

 <td> <button onclick="alertdialog()"><span class="glyphicon glyphicon-trash"> </span></button></td>
<script>
function alertdialog(){
    window.confirm("Are you sure you want to delete this post?");
}
</script>   This is my code. I need to have a callback to a PHP script when a user decides to delete a post. I think html POST is the most unobtrustive way to do this. What's the easiest / most robust way to send data to a script when the user clicks OK?   Appreciated. Mark  

I've managed to isolate a problem I'm having with my php script. It would seem the script randomly restarts itself with blank post data while it's running.

I've managed to mimick the problem using a very basic php script which just pauses and writes to a log:

<?php

$q = $_POST['q'];

if ($q==""){
  writelog ("MISFIRE!!!");
  die;
}

writelog("\n*** Error check started ***");

for ($i = 1; $i <= 50; $i++) {
   writelog ($i);
     sleep(rand(2,20));
}

 function writelog($towrite)
{
  $tdate=date('d/m/Y H:i:s');
  $file = 'log/testlog.txt';
  $current = $towrite." --- ".$tdate."\n";
  file_put_contents($file, $current, FILE_APPEND);
}

writelog("*** Error check ended ***");
?>

To rule out any problems with my AJAX htmlhttp requests, I simply send the script some irrelevant post data using Chrome's Advanced Restful client.

This is the ouput of the log from an example test run:

*** Error check started *** --- 05/06/2014 18:27:30

1 --- 05/06/2014 18:27:30
2 --- 05/06/2014 18:27:44
3 --- 05/06/2014 18:27:49
4 --- 05/06/2014 18:27:59
5 --- 05/06/2014 18:28:04
6 --- 05/06/2014 18:28:22
7 --- 05/06/2014 18:28:33
8 --- 05/06/2014 18:28:39
9 --- 05/06/2014 18:28:52
10 --- 05/06/2014 18:29:08
11 --- 05/06/2014 18:29:22
12 --- 05/06/2014 18:29:30
13 --- 05/06/2014 18:29:43
MISFIRE!!! --- 05/06/2014 18:29:46
14 --- 05/06/2014 18:29:56
15 --- 05/06/2014 18:30:07
16 --- 05/06/2014 18:30:09
17 --- 05/06/2014 18:30:15
18 --- 05/06/2014 18:30:32
19 --- 05/06/2014 18:30:52
20 --- 05/06/2014 18:30:54

Note the logged "Misfire" after the 13th entry.  This shows the script tried to run again with blank post data, the same problem I'm having in my more complex script.

Why could this be happening? It's not anyone else calling the script, nobody knows about the site and I've ruled it out by logging the IP in my real script.
