Hi

I have used TCPDF to generate documents with single values from a mysql table. Now I want to generate a calendar.
I have a table events_pbw which contains (amongst others) the fields id, date and name.

I would like to generate a pdf which lists all of the results for entries after a particular date (eg Jan 1st)

I have this:

// get data from events_pbw table
$result = mysql_query("SELECT  id, date, name
                    FROM events_pbw
                    WHERE `date` > 2011-01-01"
                    ");

while($row = mysql_fetch_array($result))
  {
    $appid = $row['id'];
    $date = $row['date'];
    $name = $row['name'];
}

But I don't know how to get the full list of results into the pdf. I'm sure this is very easy but I'm not great on php coding!

Does anyone have any examples or help they could give me?

Many thanks

Hi, I have a table of content in my page. For each row it has a check box. How do i achieve the function of when i click on submit button, those rows which are checked will be downloaded as a single pdf file. For example, for each checked row is a PDF file here. Suppose if i checked for 5 rows , 5 PDFs will be downloaded.
Can i know how can i achieve this? 
Or is it not possible to do that for TCPDF library?
If it is possible, i would appreciate if you guys could give me hints or some reading documentation to achieve this function. I have no idea how should i search for the solution for this function.  Thanks in advance

I haven't worked with TCPDF yet (PHP class for creating PDFs) but if anyone has, I'm just curious if you can reference an external CSS file to format the HTML that gets created in the PDF?

Or can you only use inline CSS?

Basically, I have a nicely formatted HTML table using a somewhat complicated external CSS file and I want to output that same table to a PDF and have it look essentially the same.

If TCPDF cannot do this, do you know of any other PDF PHP libraries that can?

Thanks,
Greg

Hi all,

I am trying to get data from MySQL to display in a html table in TCPDF but it is only displaying the ID.

$accom = '<h3>Accommodation:</h3>
<table cellpadding="1" cellspacing="1" border="1" style="text-align:center;">
<tr>

<th><strong>Organisation</strong></th>
<th><strong>Contact</strong></th>
<th><strong>Phone</strong></th>
</tr>
<tbody>
<tr>'.
$id = $_GET['id'];
$location = $row['location'];
$sql = "SELECT * FROM tours WHERE id = $id";
$result = $con->query($sql);

if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {

'<td>'.$location.'</td>
<td>David</td>
<td>0412345678</td>
</tbody>';
}
}
'</tr>
</table>';

Anyone got any ideas?

Hi
I have a table (applicant) and I am looking at producing a pdf displaying various items of data from this table.

I have succeeded in getting the look I want but in my query I use a fixed applicantid (in this case an id of 4). What I want to be able to do is to have the id cary according to the url. In other words, when someone comes from one web page to this one and the url is of the format .../pdf_production.php?applicantid=42.

I'm not sure I've explained that very well but I hope someone can help - I think this is the last thing I need to sort out.

Many thanks in advance.

The code I have so far is:

<?php require_once('../Connections/process.php'); ?>
<?php
require_once('../tcpdf/config/lang/eng.php');
require_once('../tcpdf/tcpdf.php');
     
// get data from users table

mysql_select_db($database_process, $process);
$result = mysql_query("SELECT * FROM applicant WHERE applicantid = '4'");

while($row = mysql_fetch_array($result))
  {
    $appid = $row['applicantid'];
    $idcode = $row['idcode'];
    $type = $row['type'];
    $company = $row['company'];
    $email = $row['email'];
  }
   
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); 

$pdf->SetPrintHeader(false); $pdf->SetPrintFooter(false);

// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

//set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);

//set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);

//set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO); 

//set some language-dependent strings
$pdf->setLanguageArray($l); 

// ---------------------------------------------------------

// set font
$pdf->SetFont('dejavusans', '', 10);

// add a page
$pdf->AddPage();
// create some HTML content
$txt = <<<EOD
Below are the details I require

Company type: $type
Company Name: $company
Company email: $email

EOD;


// output the HTML content
// $pdf->writeHTML($htmlcontent, true, 0, true, 0);
$pdf->Write(0, $txt, '', 0, 'L', true, 0, false, false, 0);

// $pdf->writeHTML($inlinecss, true, 0, true, 0);

// reset pointer to the last page
// $pdf->lastPage();

//Close and output PDF document
$pdf->Output('example_006.pdf', 'I');

//============================================================+
// END OF FILE

Hi all!   I'm new here, apologies that my 1st post will be a cry for help. I'm tearing my hair out with this one.   I've got this page that generates PDF's via TCPDF plugin http://www.kinho.com/lightbox/ whenever I view it in chrome it zooms in at 100% to the top left corner. The problem is I need the images to be large and suitable to print (7"x5" or thereabouts) and so the PDF isn't built to be viewed at 100%, it just looks too zoomed in. Every other browser respects the fit to width setting. My images are 1600px on their long side, pages are landscape. here's the create.php:https://dl.dropboxusercontent.com/u/14123055/PHP/create.php   Can anybody advise a workaround for chrome? many thanks!   badger

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

$firstArray = array(
'row1' => array(
'dates' => array(
'2014-01-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),
'2014-01-02' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),

)
)
);

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):

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=$subcatid\">
<span>$subcatname</span>
</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.
