PHP - Testing If An Embedded Array Exists In A $_post

Code: [Select]
$result = mysql_query("SELECT field_item_id_value FROM `content_type_ads`");

while($row = mysql_fetch_array($result)){
   echo $row['field_item_id_value'];
   echo "<br />";
    echo $result;
}
I am trying to use an "array diff()" argument and I am getting errors with it stating the above is not an array.  I have used $row and $result, and neither work.  Is this not dumping into an array properly?

Hey Guys,
I need some assistance, hopefully there is just a simple command that I am not aware of or an easy answer to this.

Suppose I have an array with x amount of values...
$arr = array("111111" => 10, "222222" => 20);
And i have a query..
mysql_query("SELECT * FROM table WHERE table.zip = "111111" ");

Suppose I want to modify the query, so it can check if table.zip exists anywhere in $arr, regardless of length of array. And Select the value that the array location refers to. So I need it to check if "111111" is anywhere in the array, and then take the value 10.

The example I am applying this to is that I have a database full of business addresses/zip codes and a database full of every zip code in country. So I have a script to get every zip within x miles, and the distance from it, but need to be able to apply it when I query my business addresses to see if it exists within x miles.

Thanks!

I'm a total noob trying to figure out how to get this function to work right.  I want to echo  for each Code: [Select]

Hi, I am a newbie in PHP (about week and a half). I'm writing a website for myself right now. I've got a problem that I cannot solve.

The website is about buying files with website custom balance. What I want to do is disable buy button if user bought this file b4. The is a table user_files that stores user id and file id.

And another table that stores files data, ID name who uploaded date time ect....

What I'm trying to do, is disabling buy button if the user has already the file.

This is what I've done :

while ($row = $rocket->fetch())
                  {
                  ?>
                    <tr>
                      <td><?php echo $row['id']; ?></td>
                      <td><?php echo $row['name']; ?></td>
                      <td><?php echo $row['uploader']; ?></td>
                      <td><?php echo $row['uploadtime']; ?></td>
                      <td><button <?php 
                      // Echo "disabled" if $row['id'] id is present in row2['file_id'] <<<<<<< Need to do this in a while.
                      ?>
                      ><a href="download.php?id=<?php echo $row['id']; ?>"></a><?php echo $row['price'] . "D$" ?></button></td> 
                    </tr>
                  <?php } ?>

What I can't do is check if the file id ($row['id']) is present in ($row2['file_id']), if yes echo "disabled";

 

Is there an easy way to dump out the contents of a $_POST array and display them on my screen?

(I'm trying to get more comfortable with what is stored in the $_POST array and how it is structured.)

Thanks,

How do I assign the entire $_POST array to a varible?

This code isn't working...

<?php
echo 'FormHandler';

class FormHandler{
private $formValues = array();

$this->formValues = $_POST;
}
?>

I am trying to post while loop array. But I dont know how to do this and I used foreach and it works for each array but doesnt loop this. My table has Que_ID, Question, choice1, choice2, choice3 and choice 4. I would like to do something like.. For each Que_id (choice1, choice2, choice3 , choice4), this should be looped for each que_id

so far I have

Code: [Select]
$counter = 1;
 while( $info = mysql_fetch_array( $sqll ))
 //))
 {
 echo "{$info['Que_ID']} <br />\n";
echo "<input type='hidden' name=\"Que_ID\" value=\"{$info['Que_ID']}\" /> ";
echo "{$info['Que_Question']} <br />\n";
echo "<input type=\"checkbox\" name=\"choice[$counter]\" value=\"{$info['Que_Choice1']}\" /> ";
echo "{$info['Que_Choice1']} <br />\n";
$counter++;
echo "<input type=\"checkbox\" name=\"choice[$counter]\" value=\"{$info['Que_Choice2']}\" /> ";
echo "{$info['Que_Choice2']} <br />\n";
$counter++;
echo "<input type=\"checkbox\" name=\"choice[$counter]\" value=\"{$info['Que_Choice3']}\" /> ";
echo "{$info['Que_Choice3']} <br />\n";
$counter++;
echo "<input type=\"checkbox\" name=\"choice[$counter]\" value=\"{$info['Que_Choice4']}\" /> ";
echo "{$info['Que_Choice4']} <br />\n";

$counter++;
How would go on to posting these while loop and display Que_ID and all the choices that are ticked for this que_ID and if its not ticked then its 0.

Hi. First timer here.

I'm trying to iterate through 5 arrays in a foreach loop. Yep, I know you'll say just use a counter that increments. Sadly, that gives me horrendous results! So, I am using the next & current methods of arrays. Thing is, it gives me bad results ( items that weren't even chosen on the next page ), or it leaves the first couple of items out. I did this :

Code: [Select]
<?php
 
$ID = array();
$NAME = array();
$PRICE = array();
$QUANT = array();
$checkCount = 0;

foreach (array_keys($_POST) as $key) 
{ 

$$key = $_POST[$key]; 

$iPos = strpos($key, "ID");

$nPos = strpos($key, "NAME");
$pPos = strpos($key, "PRICE");
$qPos = strpos($key, "QUANT");
$cPos = strpos($key, "CHECK");

if ($iPos !== false)
{
$ID[] = $$key;
}
else
{
//echo "The string ID was not found in the string ";
}

if ($nPos !== false)
{
$NAME[] = $$key;
}
else
{
//echo "The string NAME was not found in the string ";
}

if ($pPos !== false)
{
$PRICE[] = $$key;
}
else
{
//echo "The string PRICE was not found in the string ";
}

if ($qPos !== false)
{
$QUANT[] = $$key;
}
else
{
//echo "The string QUANT was not found in the string ";
}

if ($cPos !== false) 
{
$checkCount++;

if ($checkCount == 1)
{

echo "Product ID <input type = 'text' name = 'ID" . current($ID) . "' value = '" . current($ID) . "'></br>";
echo "Product Name <input type = 'text' name = 'NAME" . current($NAME) . "' value = '" . current($NAME) . "'></br>";
echo "Product Price <input type = 'text' name = 'PRICE" . current($PRICE) . "' value = '" . current($PRICE) . "'></br>";
echo "Product Quantity <input type = 'text' name = 'QUANT" . current($QUANT) . "' value = '" . current($QUANT) . "'></br>";
  }
 
  if ($checkCount > 1)
  {
echo "Product ID <input type = 'text' name = 'ID" . next($ID) . "' value = '" . next($ID) . "'></br>";
echo "Product Name <input type = 'text' name = 'NAME" . next($NAME) . "' value = '" . next($NAME) . "'></br>";
echo "Product Price <input type = 'text' name = 'PRICE" . next($PRICE) . "' value = '" . next($PRICE) . "'></br>";
echo "Product Quantity <input type = 'text' name = 'QUANT" . next($QUANT) . "' value = '" . next($QUANT) . "'></br>";
     }
    
} 
else 
{
      //echo "The string CHECK was not found in the string ";
}



}
?>

You will see I did all the processing under the CHECK if statement, the reason for this is, it is easier to identify the items ordered because they have been checked on the previous page.

How do I post a for loop array in the next page. I am printing Question ID and choices for these and would like the for loop to print Question ID and choice that are checked for these. If the choice is ticked then it shoul return a 1 if the choice is empty then it should print 0. and I would like to insert this to a new table.  How would I do this.

Code: [Select]
$intNum = 1;
$intnumber = 1;
 while( $info = mysql_fetch_array( $sqll )){
 

 echo "<input type='hidden' name=\"Que_ID\" value=\"{$info['Que_ID']}\" /> ";
  echo " $intNum, {$info['Que_Question']} <br />\n";
   $intNum++;
 ?>
 <br>
<?PHP
 for ($i =1; $i < 5; $i++) { 
 
 echo "<input type=\"checkbox\" name=\"choice[{$intnumber}]\" />{$info['Que_Choice'.$i]}"; 
  $intnumber++;
 
 }

this is my form that print the question and it works fine.

Code: [Select]
<?PHP
foreach ($_POST["Que_ID"] as $question) {
$_POST["choice"] = $choice;
echo "Question id: ".$question. $choice"<br />"; This is the post code but I know I need to do so much more but not sure how? Ayone help me or direct me to a source or tutorial or something.

I have a form that is populating fields based on a database query.  I am then trying to update the database based on any changes made in the form and passed through a POST action.

The problem I am having is with the block where I declare short variable names for the $_POST variables that will be passed when the user hits the submit button.  For each variable declaration I get an error message like this:
Quote

Encountered error: 8 in mbr_profile_updt_form.php, line 130: Undefined index: email


I have tried testing the $_POST variable using the isset function but it apparently is set but empty. 

What would be a good way to test to see if the user has pressed the submit button before I go into the processing block that is intended to handle those values from the form?

Here is where my code is at right now:
Code: [Select]
if (!isset($_POST))
{
throw new Exception('You have not filled the form out completely - please go back'
.' and try again.');   
}
else
{
//filled in so create short variable names
$email=$_POST['email'];
$first_name=$_POST['first_name'];
$last_name=$_POST['last_name'];

So ive created a forum that I got handling several different approvals. (it is used to approve or decline all submitted notes) it works fine and it even submits fine im at the part know where i process the information and do something with it, below is my form:


<form action="course_proccess.php?action=approve" method="post">
  <table align="left" border="1" cellspacing="0" cellpadding="3">
    <tr>
      <td><b>Author</b></td>
      <td><b>File name</b></td>
      <td><b>Download</b></td>
      <td><b>Suggested catagory</b></td>
      <td><b>Select Catagory</b></td>
      <td>Approve</td>
    </tr>
    
      <td><input type="text " disabled="disabled" name="tr1_author" value="MikeH" </td>
      <td><input typee="text " disabled="disabled" name="tr1_name" value="A lot of my skills set back"</td>
      <td><a href= /uzEr%20Upl0ds/cache.zip > Download</a></td>
      <td>1001 Laws - Polceing </td>
      <td><select name="tr1_scatagory">
          <option value="1"> Intro To Law </option>
          <option value="2"> 1001 Laws - Police Foundations </option>
        </select></td>
      <td><select name = "tr1_approve">
          <option value = "1"> Yes</option>
          <option value = "2"> no</option>
        </select></td>
    </tr>
      <td><input type="text " disabled="disabled" name="tr2_author" value="MikeH" </td>
      <td><input typee="text " disabled="disabled" name="tr2_name" value="MM"</td>
      <td><a href= /uzEr%20Upl0ds/Michael Heintzman.doc > Download</a></td>
      <td>1001 Laws - Polceing </td>
      <td><select name="tr2_scatagory">
          <option value="1"> Intro To Law </option>
          <option value="2"> 1001 Laws - Police Foundations </option>
        </select></td>
      <td><select name = "tr2_approve">
          <option value = "1"> Yes</option>
          <option value = "2"> no</option>
        </select></td>
    </tr>
    <input type="hidden" name="rowCount" value="2">
    <tr>
      <td><input type="submit" name="sendData" value="send"/></td>
    </tr>
  </table>
</form>



so what I do in my process file is I have a for loop for all of the "TR's" in the table and if it is approved I have an if statment and then I want to add db stuff my problem is my $_POST's are returning blank and I have no idea why. Can someone please assit me with this? (p.s i have debugged and it does get into the if approve == 1 statment.

if(isset($_GET['action'])){

if ($_GET['action'] == "approve"){

if(isset($_POST['sendData']))
{

$dataArray = array();

$row_count = $_POST['rowCount'];
for($i=1;$i<$row_count;$i++)
{

$approven = "tr".$i."_approve";
$approve = $_POST[$approven];

if($approve == 1)
{
//Move the info over to "approved files" and delete it out of newnotes
$author = "tr".$i."_author";
$location = "tr".$i."_location";
$catagory ="tr".$i."_scatagory";
$filename = "tr".$i."_name";
$submitedby = $_POST['author'];
die($submitedby);

$dataArray[]=array('author'=>$author,'fileName'=>$fileName,'Catagory'=>$catagory,'location'=>$location);
var_dump($dataArray);

}else{
//Email user saying they did not recive credits AND delete the entry

}
}

if(!empty($dataArray))
{
//now do what you want with the dataArray...
var_dumb($dataArray);
}
}

}

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.

I need to email the form http://keegenk.com/providenceltddesign/ to myself.  Right now, the email is sending and the confirmation page comes up, but the email does not have any of the data that should be collected by the form.
I'll attach the php file that I'm using to capture the variable and send it to the email address.
Any and all help is appreciated.  Thanks a bunch

Hi the above title explains it all.How to output a post array which has been given input using forms.I know you can do it my echo but what about print()
Thanks

Hi, i'm new here and hope i've finally found a forum where i can find the perfect solution for my questions.   Well since a year now i started to work with PHP and still now and then there are some things where i seize on. My question is on of those situations.   I have the following code:

if (isset($_POST)){
    
    foreach ($_POST as $key => $value){

    if (!empty($value)){
    $update_rma_detail_stmt = $dbh->prepare("UPDATE rma_detail SET $key = ? WHERE rd_rma_nr = ?");
    $update_rma_detail_stmt->bindParam(1, $value);
    $update_rma_detail_stmt->bindParam(2, $getadmrmaid);
    $update_rma_detail_stmt->execute();

    }
  } 
}

All i want is when there is an empty (not filled in) input field because it is not mandatory the foreach still continuous to the end. When i use

if (!empty($value)){

It still outputs these error:   Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 1366 Incorrect integer value: ' '   However, when i dont use i got an other error:    Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22007]: Invalid datetime format: 1292 Incorrect date value: ''   It is however so that the datetime is the very first empty field it come across when looping. I think my if (!empty($value)){ is doing the right thing but still gives error's on integers. Can it be? I allready tried to use trim() or array_filter() but because i previously never used it i dont know if i am doing it the right way so any help is welkom!   Thanks!
