passing variable in animg src tag

[Lassie]

I want to build an image with text variables.

I can get the image OK but not the text, which I need to pass in an img tag from a form.

I have not posted the form  here as I know the post field is populated.

The static string shows overlayed on the image but not the variable string passed in the query string.

Any help appreciated.

My code is as follows:-

input form

<?php
if (isset($_POST['submitted'])) {
	if(isset($_POST['AuthorName'])){
	$str=($_POST['AuthorName']);


	?><img src="http://localhost:8888/test_upload/text-create2.php?str=' . $str . '"/><?php
	}

}
?>

 

The recieving script

<?php
$str2=$_GET['$str'];
$image = ImageCreateFromPNG("http://localhost:8888/wordpress_3/wp-content/plugins/Authors2/jackets/GDL.png");
$color = imagecolorallocate($image, 0xFF, 0xFF, 0xFF);
$colorShadow = imagecolorallocate($image, 0x66, 0x66, 0x66);
$font = 'Tahoma.ttf';
$fontSize = "10";
$fontRotation = "0";
$str= "Successful Home Catering";


/* Shadow */
ImageTTFText($image, $fontSize, $fontRotation, 27, 22, $colorShadow, $font, $str );

/* Top Level */
ImageTTFText($image, $fontSize, $fontRotation, 25, 20, $color, $font, $str);

ImageTTFText($image, $fontSize, $fontRotation, 25, 100, $color, $font, $str2);

header("Content-Type: image/PNG");
ImagePng ($image);
imagedestroy($image);
?>

change

<?php
if (isset($_POST['submitted'])) {
if(isset($_POST['AuthorName'])){
$str=($_POST['AuthorName']);
?><img src="http://localhost:8888/test_upload/text-create2.php?str=' . $str . '"/><?php
}
}
?>

 

to this

 

<?php
if (isset($_POST['submitted'])) {
if(isset($_POST['AuthorName'])){
$str=($_POST['AuthorName']);
echo "<img src='http://localhost:8888/test_upload/text-create2.php?str=$str'/>";
}
}
?>

Thanks for your reply.

This gives a very small broken image I'm afraid.

Is ther e a way to check the variable is being passed?

[dragon_sa]

just echo it to the screen before

<?php
if (isset($_POST['submitted'])) {
if(isset($_POST['AuthorName'])){
$str=($_POST['AuthorName']);
echo "AuthorName=$str<br/>";
echo "<img src='http://localhost:8888/test_upload/text-create2.php?str=$str'/>";
}
}
?>

and the variable should be visable after the = sign when viewing

[Lassie]

Yes, Sorry I meant in the recieving script.

[dragon_sa]

this

$str2=$_GET['$str'];

 

should be

 

$str2=$_GET['str'];

Thank you. That works.

I will now develop this a little bit with some more vars and I also need to save the image.
