I am done with generating PDF file using FPDF in php. But the problem is how to open this pdf without the Save As option? I want to display the pdf document in the browser.
http://www.fpdf.org/en/doc/output.htm
Syntax: Output([string name] , string dest) , use I as Destination and fdpf will try to show it in the browser, if browser plugings and so on enable it
You cannot force this display, as it is up to the user to choose to display the PDF inline or systematically save them. I prefer the second option...
Now, there is a JavaScript / HTML 5 project (experimental!) to display PDF without plugin, so perhaps you can try that.
Even when using fpdf passing the output to the browser, I believe its still up to the user if they open or save it.
A solution would be to use some kind of PDF viewer, for example http://view.samurajdata.se/
Try this $pdf->Output('I', 'filename.pdf')
See the reference http://www.fpdf.org/en/doc/output.htm
Set header's content-type to 'application/pdf'. Then, most browsers will try to open it and show in-browser (or at least ask user to save or open file)
Your browser must have pdf plugin installed. If you havent done so install latest version of Acrobat Reader. If you are using fpdf, output the string instead of forcing download
For details
http://www.fpdf.org/en/doc/output.htm
Try echoing the PDF instead to using header function. The header function will force the browser to download. The echo 'might' show the pdf.

I'm creating a pdf from formdata using fpdf (http://www.fpdf.org/).
Using Jquery I'm able to send the data to the pdf-creating script, and make the pdf appear in browser.
Now I'm trying to return the pdf-data to the formpage using fpdf's option to get the pdf as a string and echoing it.
$pdf_file_contents = $pdf->Output("","S");
echo $pdf_file_contents
My question now is
How do I use this data to preview the pdf under the form?
Do I need to use an pdf-viewer or can I use an <iframe> and am I doing this the correct way by returning the variable in an echo?
I can think of two options:
Embed a PDF viewer and handle that call in JS. (Wait for the response from PHP and display the outputted file inline)
Trigger a redirect or load an iframe which displays $pdf->Output($filename,"F") from a temp file.
The result of $pdf->Output() is displayed using the browser's built-in viewer. If there is any output above that in the page FPDF will return an error to say FPDF error: Some data has already been output, can't send PDF.
FPDF error: Some data has already been output, can't send PDF
There might be some other option I'm missing but those would be my first suggestions.
I have a website now and I want to create a button on it to convert this page to PDF.
Is there any code to make this happen? I cannot find it on the internet.
So I want to have a button and when I press on it it converts the page to a .PDF file.
I do not want to use a third party website to generate the PDF's. I want to use it for internal purposes to generate files with PHP. So I need the code what can make a PDF for each page.
I use wkhtmltopdf - works very well - http://code.google.com/p/wkhtmltopdf/ there is a PHP wrapper
Updated based on comments below on usage :
How to use the integration class:
require_once('wkhtmltopdf/wkhtmltopdf.php'); // Ensure this path is correct !
$html = file_get_contents("http://www.google.com");
$pdf = new WKPDF();
$pdf->set_html($html);
$pdf->render();
$pdf->output(WKPDF::$PDF_EMBEDDED,'sample.pdf');
Use FPDF. It's a well-respected PDF-generating library for PHP that is written in pure PHP (so installing it should be dead simple for you).
Try this:
http://www.macronimous.com/resources/Converting_HTML2PDF_using_PHP.asp
It will convert HTML to a PDF using FPDF and HTML2PDF class.

What are some possible ways to save an image or make use of it that is generated from a PHP script. Using save as it does not help though.
This is not an image created by me that's why I want to avoid get_contents.
here is the picture
and here is the url
https://render01.fontshop.com/fonts/font_rend.php?idt=f&id=38005&rbe=fsifr&rt=how+do+I+save+this?&rs=38&w=500&bg=ffffff&fg=000000&tp=0.0
Just write the content of the URL to a file
<?php
file_put_contents("img.png", file_get_contents("http://render01.fontshop.com/fonts/font_rend.php?idt=f&id=38005&rbe=fsifr&rt=how+do+I+save+this?&rs=38&w=500&bg=ffffff&fg=000000&tp=0.0"));
Using file_put_contents() function. If you don't have data in variable and want to readout use file_get_contents()
Since you are not generating the image in your own code, the simplest would be a combo of file_get_contents and file_put_contents:
$url = '...'; // your url here
$data = file_get_conents($url);
file_put_conents('image.png', $data);
In this specific case the render is a PNG image, but if there's a possibility of it being a JPEG or something else then you need to somehow detect that as well. I 'm not giving any suggestions for this because there's not enough info to go by.
You can define a filename in imgpng() or the other functions to tell PHP to store the picture instead of sending it to the calling browser.
I understand you want to save it on the client, with a browser, not on the server.
"Save as" worked fine for me (Firefox 7). In Chrome you'll have to specify the extension of the filename manually. Did not test other browsers, but it should work similarly
You can do this from the terminal using the curl command.
curl -o out.png 'http://render01.fontshop.com/fonts/font_rend.php?idt=f&id=38005&rbe=fsifr&rt=how+do+I+save+this?&rs=38&w=500&bg=ffffff&fg=000000&tp=0.0'
This will save the file as out.png
use imagepng function.
It will return file to browser or save it specified location.
Need to set parameter for function to save image on specified location.
Lets say i have this string "something1,something2" and i want to download it as "text.csv", without opening new window (pop up) how could i do this from a webpage. can i dot it in JS without using this:
window.open('data:text/csv;charset=utf-8,' + str);
or do i have to use PHP for this ?
What you want to do is a bit unconventional, but it is possible.
Take a look at Downloadify. It's a JavaScript library that leans on Flash to create a file on the client side and present the file download dialog.
David Walsh has some good demos and info too on his blog.
While limited, there is also http://en.wikipedia.org/wiki/Data_Uri
So this as a url would open an image
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==
You could have javascript open this url to trigger the download
A CSV example
data:text/csv,field1%2Cfield2%0Afoo%2Cbar%0Agoo%2Cgai%0A
Just copy/paste either of those into your browser to see them work. Browser support is limited.
IE 8 for example has a 32KiB limit
is that possible to show whole php page as an image file like png or jpg ?
for example,
<img src="details.php?id=44">
just like a screenshot of the page.
Thx
<?
// details.php file
// {
// do stuff to create your image and store in $my_image
// }
header("Content-type: image/jpg");
echo $my_image;
?>
1) output the mime type in the header.
2) echo your binary data
easy!
Not in the way you're thinking. You can use the PHP ImageMagick library or the PHP GD Library to generate an image dynamically and output it, but in order to get screenshots of a page you'll really need an outside service.
it depends on what you want to show. if its html/js/css, it varies across browsers.
If its unicode text to be displayed as images, you can use GD library for the purpose
I think you are talking about taking screenshots of a url or webpage. You can you freely available like:
http://www.shrinktheweb.com/
http://picoshot.com/
There are many such freely available services. If you want to host such service on your own server. You will need to create a software which can open your browser and take screenshot of the url. Ther are some softwares available as well. I hope it helps.
