PHP - Form: $_post 2 Values From Each Checkbox And Button

Hi all

I am populating a List menu with values from Mysql table. The values are populated correctly. Once a selection is made and upon submit when I display POST submit values using print_r($_POST) the result is correct only when the value do not contain spaces. For example if the list selection is "One" the $_POST[sel] value is correct. But if the selection is "Two Three" it is only first part before space. How do I get it to give complete value as in the list.

Thanks and Regards

Hello everyone,

I'm trying to code a section of the site which is like an advertising website (i.e, gumtree) where people can post an Ad on the site and have any responses sent to them via email. The thing is that I have a form where they can enter their details and need to POST the information to the following page which is a preview page of their Ad. I have the form action returning to the same page for validation but I need the $_POST vaules to populate the following page without sending information to the database (in an effort to keep the database clean should they decide not to publish their Ad.

There are 3 pages in total CREATE AD > PREVIEW AD (where they can go back and edit if they need to) > Publish AD (where they confirm terms and send to database).  I do have session variables already set after login in and a seperate table to hold the details after they have confirmed the Ad & terms.

Any ideas would be greatly appreciated.

Thanks, L-plate

I'm trying firstly to output hidden fields based on the values of the $_POST variable.

Then after that I want to output the values again in a unordered list.

I'm using the following code:
while (list($key, $val) = each($_POST)) {
if ($key != 'Submit') {
echo '<input type="hidden" name="' . $key . '" value="' . $val . '" />';
}
}

echo '<ul>';
while (list($key, $val) = each($_POST)) {
if ($key != 'Submit') {
echo '<li><strong>' . $key . '</strong>: <span class="highlight-219ddb">' . $val . '</span></li>';
}
}
echo '</ul>';

However the <ul> appears to be blank? Can I only use the list() function once on a particular variable?

Well I have a script file that loads lots of info from a form using $_POST[] method, which is quite tedious:

Code: [Select]
  $act = $_POST["act"];
          $page = $_POST["page"];
  $id = $_POST["id"];
  $category = $_POST["category"];
          $itemname = $_POST["itemname"];
          $description = $_POST["description"];
  $imageurl = $_POST["imageurl"];
  $existingimageurl = $_POST["existingimageurl"];
  $function = $_POST["function"];
  $target = $_POST["target"];
  $value = $_POST["value"];
  $shop = $_POST["shop"];
          $price = $_POST["price"];
  $tradable = $_POST["tradable"];
  $consumable = $_POST["consumable"];

I was wondering if there is a way to write one or two simple lines of code to load all variables stored in superglobal array $_POST[] efficiently. The point is to store all values within $_POST[] to an array called $item[], what I was thinking about is:

Code: [Select]
foreach($_POST = $key as $val){
  $item['{$key}'] = $val;
}

Seems that its not gonna work, so I wonder if anyone of you have ideas on how I am able to simplify my code with 10-20 lines of $_POST[] to just 2-3 lines. Please do lemme know if this is possible, thanks.

Hi all,

I'm looking for some pointers in regards to my form..

How would  I firstly trim the $_POST value of the variables that come through via the form (I'm only using one for now)..I know I'm making a right dogs dinner of it. 

In my head I'm thinking, trim all the posts first before i even assign a variable to it ( i dont know if thats possible), then use an array for when more values start coming through via the form. You know as i make a contact form that requires more data from the user..

 

<?php
require_once '../connection/dbconfig.php';

include_once('../connection/connectionz.php');
//get the values



//Get the request method from the $_SERVER
$requestType = $_SERVER['REQUEST_METHOD'];
//this is what type
//echo $requestType ;

if($requestType == 'POST') {
	
	//now trim all $_POSTS
	$search_products = trim($_POST['search_products']);

	//
	if(empty($search_products)){
		echo '<h4>You must type a word to search!</h4>';
	}else{
		$make = '<h4>No match found!</h4>';
		
		$new_search_products = "%" . $search_products . "%";

		$sql = "SELECT * FROM product WHERE name LIKE ?";
		//prepared statement
		$stmt = mysqli_stmt_init($conDB);
		//prepare prepared statements
		if(!mysqli_stmt_prepare($stmt,$sql)) {
			echo "SQL Statement failed";
		}else{

			//bind parameters to the placeholder
			mysqli_stmt_bind_param($stmt, "s", $new_search_products );
			mysqli_stmt_execute($stmt);

			$result = mysqli_stmt_get_result($stmt);
			echo'<h2> Search Result</h2>';
			
			echo 'You searched for <strong><em>'. $search_products.'</em></strong>';
			while($row = mysqli_fetch_assoc($result)){
			echo '<h4> (ID						: '.$row['pid'];
			echo ') Book Title						: '.$row['name'];
			echo '</h4>';
		}
	}

}
	}
;?>

 

If any one can shed some light on this, or some pointers..that would be very nice...

Thanks

Darren

The code below is what I have this far. In some way when I click the send button it always gives the last username in the table in the $_Post variable. Can anyone help me please.

Thnx Ryflex

what would be the $_POST variable name for a radio button option?

Whenever I try and post a form with radio buttons like this

<input type="radio" name"whatever" value="0">

and I do a

var_dump($_POST)

it always shows 

array(11) {["whatever"]=> string(2) "on" }

but this works and will display 1 in the var_dump

<input type="radio" name"whatever" value="1">

Why is this. I need the value set to 0 because that's the value going into the database. I don't really want to do a str_replace just to replace "on" with "0"  

Is is possible to give multiple values in a single checkbox?
i need to have a checkbox that holds multiple values.

Help Anyone..

I have a form and on each input I set the value as the post variable of it's self.  I do this so that if the user submit the form and it has errors they haven't lost the data they have inputted.  For example

<input name="input1" type="text" value="<?php echo($_POST['input1']); ?>" />

This works fine for text field and textarea's but how do I retain the value of radio boxes and checkboxes?

I have  a form that has a list of checboxes, each checkbox has multiple values. IE. Checkbox1 has Date 1 and Cost1. Checkbox2 has Date2 and cost2 and so on.

This is what I have in form.

echo "<input type=checkbox name=service_id[] value=".$id."><label>".$description."</label> Date:<input type=date name=date[] value=".date('Y-m-d').">Date:<input type=number name=cost[] value=".$cost."><br>";

When i run the for loop to insert the values into a table i have this.

foreach($_POST['service_id'] as $key => $value){
$cat1=$_POST['service_id'][$key];
$cat2=$_POST['date'][$key];
$cat3=$_POST['cost'][$key];}

The problem is that when I select certain boxes (ie, checkbox #2), it inserts Date1 and Cost1 but does use the correct service id (ie checkbox)
I am clearly not storing the values into the array correctly. Any thoughts?

 

Basically i made a form with checkbox using post.. here's the form

Code: [Select]
<?php echo '<form name="formupload" method="post" action="val3.php">';
echo '<input type="image" src="images/reject.png" name="test" width="170" height="35" border="0" value="reject">';
echo "<table border=\"5\" >";
echo "<tr><th>List of Instructor</th>";
    if(mysql_num_rows($result)) 
    { 
    while($row = mysql_fetch_assoc($result)) 
    { 
echo "<tr><td>";
    echo "<input type='checkbox' name='list[]' value='".$row['fullname']."'>" .$row['fullname']."<br/></td>"; 
    echo "</tr>";
   } 

}
    else {
    echo "<tr><td>No one to Approve</td></tr>";  
    } 
echo '</form>'; ?>

Then my val3.php will output the values of the checked checkbox.

here's the code.
Code: [Select]
<?php

foreach ($_REQUEST['list'] as $checkbox)
{
echo $checkbox;
echo "<br/>";
}


?>




Now i don't know how to insert those values to my database.. help pls.

Trying to get a form to display checked and unchecked values based on what is in the database.

Hard coded form works fine. I implode the array and it goes into the database as a comma delimited string.

But I need to let users edit the checkbox values, so I need to create the form by exploding the string, iterating through the array, and outputting the checkbox form elements.

Here's what I have...

Code: [Select]
<p>Specialization:
<p>
<?php

//echo $session->userinfo['specialization']; THIS DISPLAYS THE STRING CORRECTLY
 
$aSpecialization = array('Automotive', 'Aerospace', 'Biotech/Life Sciences', 'Chemicals', 'Damages Analysis', 'Electronics', 'Litigation', 'Manufacturing ', 'Materials', 'Medical Devices', 'Mobile Applications', 'Patent Prosecution', 'Physics', 'Renewable Energy', 'Semiconductors', 'Software', 'Telecommunications', 'Utilities');
 
//converting comma separated into array using explode function

  $dbspecialization= explode(',',$session->userinfo['specialization']);
  
  // echo $dbspecialization; THIS IS CONFIRMED AS AN array
 
  foreach ($aSpecialization as $specialization) {
 
     if(in_array($specialization,$dbspecialization)) {
      echo '<input name="specialization[]" type="checkbox" value="$specialization" CHECKED> $aSpecialization[] <br />';
          } else {
      echo '<input name="specialization[]" type="checkbox" value="$specialization"> $aSpecialization[] <br />';
          }
    }
?>

But the output I get is...

Code: [Select]
<input name="specialization[]" type="checkbox" value="$specialization" CHECKED> $aSpecialization[] <br />

<input name="specialization[]" type="checkbox" value="$specialization"> $aSpecialization[] <br />

<input name="specialization[]" type="checkbox" value="$specialization"> $aSpecialization[] <br />

etc...


What am I missing?

What I have is a page with a list of cars, each with a checkbox next to them.

Code: [Select]
<?php
$sth = null; $count = 0;
$sth = $dbh->prepare("SELECT * FROM garage WHERE warehouse_id = ? ORDER BY car_name ASC");
$sth->execute(array($_POST['ware_id']));
echo "<table>";
echo "<tr>";
echo '<td>Choose Vehicles:</td>';
echo "</tr>";
echo "<tr>";
echo "<td>";

echo "<form action='warehouse_ship_3.php' method='POST'>";
while($row = $sth->fetch()){
echo "<input type='checkbox' name='cars' value='".$row['uci']."' /> ID: ".$row['uci'].", ".$row['car_year']." ".$row['car_name']."<br />";  
}
echo "<input type='hidden' name='ware_id' value='".$_POST['ware_id']."' />";
echo "<hr />";
echo '<div class="center"><input class="myButton" type="submit" name="submit" value="Next" /></div></form>';
echo "</td>";
echo "</tr>";
echo "</table>";

?>
That works fine. What I'm trying to do with this second page, is select all the car's info from a table called "garage" which stores data for all the cars (car name, year, etc) and display it. UCI stands for Unique car id, every car has a different id. It works when the user only selects one car on the previous page, but if they select two or more cars, only the car with the highest UCI number shows up. How would I work it to display info on every car that they selected?

Code: [Select]
<?php
  if(empty($_POST['cars']))
  {
    echo("You didn't select any cars.");
  }
  else
  {
$sth = $dbh->prepare("SELECT * FROM `garage` WHERE `uci` = ?");
$sth->execute(array($_POST['cars']));
while($cars = $sth->fetch()){

echo"
".$cars['uci'].", ".$cars['car_year']." ".$cars['car_name']."
";
}
  }
?>
