I am trying to put together a small web application that will dynamically generate a tag to be printed and put onto an actual physical item which included the name of the product, the price, a description, and the barcode. I want these attributes to be edited via a form filled out by an employee. the barcode php is some pre-fab php code that automatically generates an image based on the user input using a form. since I know exactly what I want as the variables I only need to change the number within the link to have it produce the proper barcode for the item. In addition I am having problems getting the values of my text files to change. I think that my host may have the fopen, function disabled which I have to check on but I could use some help getting around this.
Here is what I am using to try and create the final image
Code: Select all
<?php
header("Content-type: image/png");
$barcode = "barcode.txt";
$barcodenum = trim(file_get_contents($barcode));;
$image = imagecreatefrompng("../tag.png");
$image02 = imagecreatefrompng("/barcode/html/image.php?code=ean13&o=2&t=30&r=3&text="$barcodenum"&f1=Arial.ttf&f2=15&a1=&a2=&a3=");
$Name = "name.txt";
$ProductName = trim(file_get_contents($Name));;
$Price = "price.txt";
$ProductPrice = trim(file_get_contents($Price));;
$Desc = "desc.txt";
$ProductDesc01 = trim(file_get_contents($Desc));;
//imagecolorallocate($image, R, G, B) in HEX values
$font_black = imagecolorallocate($image, 2, 1, 8);
$font_red = imagecolorallocate($image, 205, 68, 75);
//($image, fontsize, rightindent, downindent, data, txtcolour)
imagestring($image, 10.75, 80, 140, $ProductName, $font_black);
imagestring($image, 20, 80, 225, $ProductPrice, $font_red);
imagestring($image, 8, 80, 300, $ProductDesc01, $font_black);
imagestring($image, 0, 143, 690, $image02);
imagepng($image);
imagedestroy($image);
?>Code: Select all
<?php
$name = "/txt/name.txt";
$file01 = fopen($name, "w")or die("can't open name.txt");
if($_POST['name']) fwrite($file01, $_POST['name']);
fclose($file01);
$price = "/txt/price.txt";
$file02 = fopen($price, "w")or die("can't open price.txt");
if($_POST['price']) fwrite($file02, $_POST['price']);
fclose($file02);
$desc = "/txt/desc.txt";
$file03 = fopen($desc, "w")or die("can't open desc.txt");
if($_POST['desc']) fwrite($file03, $_POST['desc']);
fclose($file03);
$barcode = "/txt/barcode.txt";
$file04 = fopen($barcode, "w")or die("can't open barcode.txt");
if($_POST['barcode']) fwrite($file04, $_POST['barcode']);
fclose($file04);
?>
<form action="<?=$PHP_SELF?>" method="post">
<p>Name:
<input type="text" name="name"/>
</p>
<p>Price:
<input type="text" name="price"/>
</p>
<p>Description:
<input type="text" name="desc"/>
</p>
<p>Barcode :
<input type="text" name="barcode"/>
</p>
<p>
<input type="submit"/>
</p>
</form>any help with this is much appreciated.
