PHP - While Loop Error.

hi i am trying to fetch all my data from table here is the code

function premiumview($cn,$table)
	{
		$table=mysqli_real_escape_string($cn,$table);
		$result=$cn->query("select * from $table");
		if($result->num_rows >0)
		{
			while($f=$result->fetch_all(MYSQL_ASSOC))
			{
				$result[]=$f;
			}
			return $result;
		}
		else
		{
			return $result=$cn->error;
		}
	}

and the error is   Fatal error: Cannot use object of type mysqli_result as array ( in while loop line )   What i am doing wrong?

I get the error:
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in D:\mypubspace.com\wwwroot\phpsite\pubs.php on line 95

$towns  = "SELECT DISTINCT rsTown, COUNT(PubID) As PubCount FROM pubs GROUP BY rsTown  ORDER BY rsTown ASC";
$townresult = mysql_query($towns) or die(mysql_error().'<br>SQL: ' . $towns);


echo <<<EOF

}
</select>
</form>

Please help

Hello all,  I'm new to PHP and new to this forum (although I have benefitted from your help already -cheers!). However,  this time I cannot find the answer I need/recognise/understand..

I have a form and want to conduct tests on each field returning an error message as a session variable if the test fails. The test will be different for some of the fields, and the error message is specific to each field. If there is an error in any one of the fields I want to be redirected to a failure page where all of the error messages are displayed,  otherwise I am sent on to another page.

I have already written and tested a function to sanitise the incoming form data,  so that's not a problem - it's just how to loop through and test.

I can guess that there are many ways to do this but I need to understand why one option is better than another,  and follow the syntax used (it's all part of my steep learning curve)

The approach I have thought to use is to create an array holding the field name, the test and the message,  then loop through using foreach, applying the array values into the test and creating the error message....but it's not working for me.

The other method is to declare a variable $Stop='No' and if the loop identifies an error, part of the output is to change this to 'yes' and through that redirect to the error page.

I'd really welcome your advice and tuition....cheers.. my code so far is...

Code: [Select]
$Stop='No';
$StaffPassCheck=sanitisealphanum($_POST['PasswordCheck']);

$Errors[0]['value']= sanitisealphanum($_POST['FirstName']);
$Errors[0]['message']='Please re-enter your name';
$Errors[0]['test']=($StaffFname="");

$Errors[1]['value']= sanitisealphanum($_POST['Surname']);
$Errors[1]['message']='Please re-enter your surname';
$Errors[1]['test']=($StaffSname="");

$Errors[2]['value']= sanitisealphanum($_POST['Post']);
$Errors[2]['message']='You must select an option';
$Errors[2]['test']=($StaffPost="Select Value");

$Errors[3]['value']= sanitisealphanum($_POST['Username']);
$Errors[3]['message']='You must select an option';
$Errors[3]['test']=($StaffUser="");

$Errors[4]['value']= sanitisealphanum($_POST['Password']);
$Errors[4]['message']='Please re-enter your password';
$Errors[4]['test']=($StaffPass="");

$Errors[5]['value']= sanitisealphanum($_POST['PasswordCheck']);
$Errors[5]['message']='Sorry, your passwords do not match';
$Errors[5]['test']=($StaffPass===$StaffPassCheck);

foreach ($Errors as $key => $Value){
if ( $Errors['test']=true ){
$Stop='Yes';
return $_SESSION[$key]=$Value['message'];
}
}

if ($Stop='Yes'){
header('Location.test.php');
die();
}else{
header('Location.indexp.php');
}

I'm getting an invalid argument error for my While loop.  I can't figure out why. 

Code: [Select]
$sql="SELECT * FROM schools ORDER BY class DESC,sectional ASC,team ASC";

$results = mysql_query($sql);

while ($team = mysql_fetch_assoc($results)) {

echo $team['school'] . '<br>';

}


Here is the error:

Hey.   So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:

Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each.   And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it..

$placeDataHere = array();
foreach($firstArray as $key => $dates) {
foreach($dates as $date => $values) {
foreach($values as $key => $value) {
$placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value;
//Followed by another ~50-70 lines of processing the 3 loop's data..
...
...
....
....
....
....
....
....
}
}
}

Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested.   This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance.   In short my question is, are there any better methods of handling this with the data setup we currently have?

Below is my output on the browser:

    Student: Kevin Smith (u0867587)
    Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade
    Year: 3
   
   
    Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B
   
    Session: AAB Session Mark: 72 Session Weight Contribution 20%
   
    Session: AAE Session Mark: 67 Session Weight Contribution 40%


    Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B
   
    Session: AAD Session Mark: 61 Session Weight Contribution 50%

Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this.
   
    Below is the code:

Code: [Select]
    $sessionMark = 0;
    $sessionWeight = 0;
    $courseMark = 0;
   
    $output = "";
   
    $studentId = false;
    $courseId  = false;
    $moduleId  = false;
   
    while ($row = mysql_fetch_array($result))
    {
   
   
    $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']);
    $sessionWeight  += ($row['SessionWeight']);
        $courseMark = ($sessionMark /  $sessionWeight * 100);
   
          if($studentId != $row['StudentUsername'])
        {
   
            //Student has changed
            $studentId = $row['StudentUsername'];
   
            $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n";
   
        }
             
        if($courseId != $row['CourseId'])
        {
   
            //Course has changed
            $courseId = $row['CourseId'];
   
            $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong>  <br><strong>Year:</strong> {$row['Year']}</p>\n";
   
        }
   
        if($moduleId != $row['ModuleId'])
        {
   
            //Module has changed
            if(isset($sessionsAry)) //Don't run function for first record
            {
   
                //Get output for last module and sessions
                $output .= outputModule($moduleId, $moduleName, $sessionsAry);
            }
   
            //Reset sessions data array and Set values for new module
   
            $sessionsAry = array();
            $moduleId    = $row['ModuleId'];
            $moduleName  = $row['ModuleName'];
        }
             
        //Add session data to array for current module
             
        $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']);
             
    }    //Get output for last module
   
    $output .= outputModule($moduleId, $moduleName, $sessionsAry);
   
    //Display the output
    echo $output;
I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72?

Hey guys,

Got another question im hoping someone can help me with.

I have a foreach loop (for use in a mysql query):

   foreach ($interests as $interest) {
       $query .= "($id, $interest), ";
   }

problem is i do not want the comma(,) in the last loop.

Is there some kinda of function i can use so it does not insert it on last loop?

Or should i just use a for loop with a nested if loop? something like ;

   for($i=0; $i < count($interests); $i++){
      $query .=
      "($id, '$interests[$i]')";
      if($i + 1 < count($interests)) {
         $query .= ", ";
      }
      }


Cheers guys

I am working to echo the results in a while or for loop... Both of my sample codes work, but the results are wrong!

The while loop ONLY echos a result IF the first record in the postings table matches the id passed (does not display a result unless the first record has a match)

The if loop displays ALL listings with the same name (counts them all) so there are no unique listings!


<?php

$posts_by_city_sql = "SELECT * FROM postings WHERE id='$_GET[id]'";
$posts_by_city_results = (mysqli_query($cxn, $posts_by_city_sql)) or die("Was not able to grab the Postings!");

/* While Loop  */
while($posts_by_city_row = mysqli_fetch_array($posts_by_city_results)) {
echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>";
}

/* For Loop  */
$posts_by_city_row = mysqli_fetch_array($posts_by_city_results);
 
for ($i=0; $i<sizeof($posts_by_city_row); $i++) {
echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>";
 }

?>

Results with for loop (there are 7 total unique book names, but it's just counting the first match on id 7 times like below):

I am a new developer, trying to figure out what causing a memory error. The code goes through registered appointments and depends on the service ID, I have to free a 45 minutes for another service to be booked. Now, once I book an appointment for any of the services that can have 45 minutes free spot, the website takes forever to load the hours but doesn't show them, instead I get this error

Hello all,   Appreciate if you folks could pls. help me understand (and more importantly resolve) this very weird error:     Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ASC, purchase_later_flag ASC, shopper1_buy_flag AS' at line 3' in /var/www/index.php:67 Stack trace: #0 /var/www/index.php(67): PDO->query('SELECT shoplist...') #1 {main} thrown in /var/www/index.php on line 67   Everything seems to work fine when/if I use the following SQL query (which can also be seen commented out in my code towards the end of this post) :  

$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
           FROM shoplist, store_master, item_master
           WHERE     shoplist.store_id = store_master.store_id
                   AND shoplist.item_id = item_master.item_id";

  However, the moment I change my query to the following, which essentially just includes/adds the ORDER BY clause, I receive the error quoted above:

$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name 
		FROM shoplist, store_master, item_master 
		ORDER BY purchased_flag ASC, 
				purchase_later_flag ASC, 
				shopper1_buy_flag ASC, 
				shopper2_buy_flag ASC, 
				store_name ASC) 
		WHERE 	shoplist.store_id = store_master.store_id 
				AND shoplist.item_id = item_master.item_id";

In googling for this error I came across posts that suggested using "ORDER BY FIND_IN_SET()" and "ORDER BY FIELD()"...both of which I tried with no success.   Here's the portion of my code which seems to have a problem, and line # 67 is the 3rd from bottom (third last) statement in the code below:  

                    <?php
                        /*
                        $sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name

                                WHERE     shoplist.store_id = store_master.store_id
                                        AND shoplist.item_id = item_master.item_id";
                        */
                    
                        $sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name

                                ORDER BY FIND_IN_SET(purchased_flag ASC,
                                                 purchase_later_flag ASC,

                                WHERE     shoplist.store_id = store_master.store_id
                                        AND shoplist.item_id = item_master.item_id";
                        $result = $pdo->query($sql);

Good Evening -  I am in the process of trying to call back a list of categories and sub categories using a WHILE LOOP inside of a WHILE LOOP. It works on a different part of the site within the admin panel but not here. Here it only calls one sub category and moves on to the next parent category instead of finishing the loop and pulling all sub categories out...

// CATEGORIES

$query  = "SELECT * FROM cat";
$result = mysql_query($query);



while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{

$catid = $row['id'];
$catname = $row['name'];

$output .= "<li class=\"level0 nav-2 parent\" onmouseover=\"toggleMenu(this,1)\" onmouseout=\"toggleMenu(this,0)\">
<a href=\"product.php?cat=$catid\">
<span>$catname</span>
</a>\n";


$querynav = "SELECT * FROM subcat WHERE pid = '$catid'";
$resultnav = mysql_query($querynav);

while($array = mysql_fetch_array($resultnav, MYSQL_ASSOC))
{

$subcatid = $row['id'];
$subcatname = $row['name'];

$output .= "<ul class=\"level0\">
<li class=\"level1 nav-2-1 first\">
<a href=\"product.php?cat=$catid&subid=$subcatid\">

</a>
</li>
</ul>
</li>";
}

Hi,

I am new to PHP. Can someone explain me clearly how to use while loop inside while loop to print "*" in square shape.

Thank you for your help.

A WHILE loop in a FOR loop problem

Script about links and sublinks from 1 table.

In fact 2 questions about that.
1) In the FOR loop I have for example to do the loop 3 times. (needs to find 3 results withing the loop with if and else)
When first time, he's gonna search within the WHILE loop that holds (for example) 10 records of the DB in a variable.
He needs to search for rowid number 5, he found it
He goes out of the WHILE loop and goes searching again but now for rowid number 2
 
Now it seem that the WHILE loop start searching for number 2 but won't start from his first row in the variable (10 rows from the db ).
He start at row number 6 instead of beginning all over again !!!

-> so the order of the numbers of rows MUST be in an ascending order, ortherwise he won't find them all ! But the numbers I have are NOT in an ascending order !!!
Why doesn't the WHILE loop begin again from his row 1 in the variable ?

FOR loop
{
   WHILE loop    {   content here,     break;  }
 }


2) even when I get all the result in an ascending order, he won't go doing a second search but with a different rowid number that he gets from the FOR loop.
It is giving me back indeed the right new rowid number,  but the WHILE loop is doing nothing. 
I have put many echo "..."; and other stuff for checking but can't find the cause !

Here's the code :

Code: [Select]
// $ResultShow = 10 rows from mysql db
if(isset($ResultShow)){

if (mysql_num_rows($ResultShow) >= 1){


//$linksuborder = "2,3,4";
$array1 = explode(",", $linksuborder);
sort($array1);

for ($n = 0;  $n < count($array1);  $n++){ // searchin for the right row id in the variable $ResultShow where we find the numbers for next loop
$r1 = each($array1);

While($Row2 = mysql_fetch_array($ResultShow))  {
 
if($Row2["linkid"] == $r1['value'])  // found it, now look for the numbers that we'll put in an array
{  echo "---here the content---"; 

// linksuborder is where numbers from row id's are stored like  5,2,8
//now put them in an array
$array2 = explode(",", $Row2["linksuborder"]);
        sort($array2);

for ($n2 = 0;  $n2 < count($array2);  $n2++){
$r2 = each($array2);

////// here searching for the sublinks //////
While ($Row3 = mysql_fetch_array($ResultShow))
{
if($Row3["linkid"] == $r2['value']) // search for the right row id within the variable $ResultShow
{
echo "---here the content---";
  break; // found it, so no need to do the rest of the loop
 
} // end if
} //end while
////// end searching for sublinks //////

}  // end for
}  // end if

else
{
echo "--- content here ---"; 
}
 


}  // end while
}  // end for


} //end if
} // end if


Table :

linkid     linksuborder     linktitle
1                  2,3,4   
2                  9,7,8           mainlink1
3                  10               mainlink2
4                                     mainlink3
5
6
7                                      sublink3
8                                      sublink2
9                                      sublink1
10                                    sublink4

-> linksuborder 2,3,4 are the row id's for the mainlink
-> than we put the numbers 9,8,7  (also row id's)  mentioned in row linkid 2  also in a new array
-> now we can search for the sublinks
-> get the details from row linkid 9, than 7, than 8

-> First mainlink is compleet, now go to row linkid 3 to do it all over again for the next mainlink...


RESULTS from an sorted array -> sort($linksuborder);
-------------------------------------------------------------
mainlink1 : sublink1, sublink2, sublink3

mainlink2  : **no result back  but it should *

mainlink 3 : **no result back  but it should *
