reload a page

@SamKookApr 27.2004

is there another way to reload a page than this :
header(“Location:”.$_SERVER[‘PHP_SELF’].”?id=1&Section=”.$_GET[“Section”]);

Cause it say the header is already sent and I don’t think i can call it before any output

[code=php]
 <a href="<?php echo ($_SERVER["PHP_SELF"] ."id=1&Section=". $_GET["Section"]); ?>" title="Reload the current page.">[Reload]</a>
 [/code]

@SamKookauthorApr 27.2004 — #and if I want to reload it automatically?

@JonaApr 27.2004 — #[font=arial]Why would you want to output something to the browser if you are going to redirect it, anyway? Why not just redirect it? Then you wouldn't have to worry about your headers problem. If you want a timed redirection, use JavaScript.[/font]

@SamKookauthorApr 27.2004 — #and if I don't want to use javascript...

i guess i'm screw up

@violent_jApr 27.2004 — #you can use a meta-tag (place it in the <HEAD> section) like this:

<META HTTP-EQUIV="Refresh" CONTENT="3;URL=http://www.some.org/some.html">

which means that the page redirects to http://www.some.org/some.html within 3 seconds

@JonaApr 27.2004 — #[font=arial]Violent J, you should not use META refreshes.[/font]

[i]From the W3C WCAG 1.0 Guidelines, section 7.4[/i]

[b]Until user agents provide the ability to stop the refresh, do not create periodically auto-refreshing pages.[/b]

[i]From the W3C WCAG 1.0 Guidelines, section 7.5[/i]

[b]Until user agents provide the ability to stop auto-redirect, do not use markup to redirect pages automatically. Instead, configure the server to perform redirects.[/b][/quote]

[font=arial]Edit: The reason it is valid to use JavaScript for redirection, although not rely on it, is because it is not markup (the META refresh tag is), and it can be disabled.[/font]

@JonaApr 27.2004 — #[font=arial]It looks like your EffacerImage function is not returning anything, so the output to the form wouldn't be correct. You should use a return statement.[/font]

[code=php]
 function EffacerImage()
 {
 $default = "1"; # default section
 if(isset($_GET["Section"])) {
 return ($_SERVER["PHP_SELF"]."?id=1&Section=". $_GET["Section"]);
 }
 else {
 return ($_SERVER["PHP_SELF"]."?id=1&Section=". $default);
 }
 }
 [/code]

@SamKookauthorApr 27.2004 — #Your right and it solved my problem.

Thanks

@violent_jApr 27.2004 — #hmm .. i've never heard about these accessibility guide lines, but on this forum it seems like a holy god !

but i'll take it in consideration ?

@Jona: Nice sig ?

[/offtopic]

@JonaApr 27.2004 — #[font=arial]SamKook, I'm glad the problem has been resolved. ?

Violent J, many people have not heard of accessibility. In these forums, many have been taught to design with CSS and semantic markup, rather than using tables for layout. This is also in the [url=http://www.w3.org/TR/WCAG10/]Web Content Accessibility (WCAG) 1.0 guidelines[/url]. An accessible Web site is one that anyone can access, whether blind or dyslexic or whatever.

Also, thanks for the comment on the signature. ? Have you checked out my links page? You should find many of those links very helpful, as almost all of them will agree with or aggressively promote accessibility.[/font]
