hey guys i have been doing some code on php ..but its not giving me the output which i expected ..The code is
<html>
<body>
<form action="images.php" method="post">
Enter image Name :<input type="text" name="imagename">
<br></br>
<input type="submit" name="sumbit">
<br></br>
</form>
</body>
</html>
In this html code user is allowded to type his name so that the image is generated according to the name..
<?php
$name = $_POST['imagename'];
if($_POST['imagename'] != ''){
header("Content-Type: image/png");
$name = $_POST['imagename'];
$im = @imagecreate(800,600);
$background_color = imagecolorallocate($im, 0xFF, 0xCC, 0xDD);
$text_color = imagecolorallocate($im, 133, 14, 91);
imagestring($im, 5, 300, 300, "$name", $text_color);
imagepng($im);
imagedestroy($im);
}
else echo "no image created";
?>
This php code generates the image accrding to the name given..
The image is generated fine with this piece of codes but what i need is that the image created must appear on the center of the browser ...i have tried it using <img src="file.php> on the html file..but it didnt worked ..
It will be really helpful if you guys find me a solution..Thanks in advance
Here you'll find an example of how to center text in a handmade image. Citing that page, you should do:
<?php
$fw = imagefontwidth(5); // width of a character
$l = strlen("$name"); // number of characters
$tw = $l * $fw; // text width
$iw = imagesx($im); // image width, 800 for your case
$xpos = ($iw - $tw) / 2;
$ypos = 10;
imagestring ($im, 5, $xpos, $ypos, "$name", $color);
//...
?>
If you want to center your image in the browser, you need html and css.
I would recommend that instead of displaying the image directly using header("Content-Type: image/png");, you save the image to a file.
Then your script can output html and include the image in an image tag or as a background image. That image can be centered in the browser easily using css.
