The scenario is I am going to pull some data from the database and output it through pdf. I use FPDF
to make it happen and I am on the part where I need to getthe height from the database and display it according to color.
For example:
MY PROBLEM IS I'm trying to insert switch case
inside a while loop
to put the height on the table where some other data are being displayed. The picture below shows where I want to implement the colored cells . It should be implemented at the "SS Height" column.
But it doesn't work and gave me this error.
This is my codes.
<?php
require('connection.php');
$sql="SELECT * FROM table ORDER BY ssh REGEXP '^[^A-Za-z0-9]' ASC, ssh DESC";
$records=mysql_query($sql);
$fetch = mysql_fetch_array($records);
require("library/fpdf.php");
$pdf = new PDF('p', 'mm', 'Legal');
$title = 'Storm Surge Warning';
$pdf->SetTitle($title);
$pdf->AliasNbPages('{pages}');
$pdf->SetAutoPageBreak(true,25);
$pdf->AddPage();
$pdf->SetBorders(array('LT', 'LT', 'LT', 'LT', 'TLR'));
$pdf->SetWidths(array(30, 27, 35, 51, 51));
$pdf->SetAligns(array('C', 'C', 'C', 'L', 'L'));
$pdf->SetFont('Arial', 'B', 10);
$pdf->Row(array("SS Height",
"Provinces",
"Low Lying Coastal Areas in the Municipalities of:",
"IMPACTS",
"ADVICE/Actions to Take"), 1);
$pdf->SetFont('Arial', '', 11);
while($row = mysql_fetch_array($records)){
$pdf->Row(array(
switch ($row['ssh']) {
case '2-3Meters' :
$pdf->SetFillColor(204, 153, 0);
$pdf->Cell($row['ssh'], 1, 1, 'L', TRUE);
break;
case '1-2Meters' :
$pdf->SetFillColor(255, 255, 0);
$pdf->Cell($row['ssh'], 1, 1, 'L', TRUE);
break;
case '<1Meter' :
$pdf->SetFillColor(51, 153, 255);
$pdf->Cell($row['ssh'], 1, 1, 'L', TRUE);
break;
default:
$pdf->Cell($row['ssh'], 1, 1, 'L', FALSE);
break;
}
$row['provi'],
$row['muni'],
$row['impact'],
$row['advice']), 1);
}
$pdf->SetBorders(array('T', 'T', 'T', 'T', 'T'));
$pdf->Row(array('','','','',''), 1, false, 1);
$pdf->OutPut();
?>
Your switch (TRUE) should use the field with the height probably something like the code below:
switch ($row['ssh'] ) {
case '2-3Meters' : {
$pdf->SetFillColor(204, 153, 0);
$pdf->Cell($row['ssh'], 1, 1, 'L', TRUE);
break;
}
case '1-2Meters' : {
$pdf->SetFillColor(255, 255, 0);
$pdf->Cell($row['ssh'], 1, 1, 'L', TRUE);
break;
}
case '<1Meter' : {
$pdf->SetFillColor(51, 153, 255);
$pdf->Cell($row['ssh'], 1, 1, 'L', TRUE);
break;
}
default:
...
Anyway, without knowing how the FPDF API works, it seems it just retains global states.
So call, the switch + colorization first (an array map would be simpler), then add the ->Cell, and lastly the ->Row, as in:
while($row = mysql_fetch_array($records)){
switch ($row['ssh']) {
case '2-3Meters' :
$pdf->SetFillColor(204, 153, 0);
…
}
$pdf->Cell($row['ssh'], 1, 1, 'L', TRUE);
$pdf->Row(array(1,2,3,4,1));
}
