Topic:

JavaScript;;PHP Scripting Language

I have extract the remote site html page by php curl() at my server and echo output into my iframe that will
help to control the remotesite's content height or width when visitor resize iframe or some other
host javascript function can be working on php curl() output for remote site page
That will help to solve the cross-domain issue

In one my target remote site link,http://help.dottoro.com/ljrmdnar.php, I would like to do so,
but display result is something strange after echo output from php program at http://www.mysite.com/curlex.php in my FIrefox ,
any menu bar icon can NOT be click-ed at area around "HOME CSS Javascript Appendix" and report javascript error
on line 105, Tree.active.Tree is undefined from FireBug in firefox when one of menu icon is clicked.

So I made a test, save the php curl output in Firefox into ANSI file such as C:curloutput.html and run it in FIrefox and
the problem is gone and any click on the menu bar is activated. this test proves the problem is NOT related to
path or domain name issue since all full domain and path name is specified in all related tag in html after viewing its html code.
And also try to send "curloutput .html" into my server, and run it in Firefox at www.mysite.com/curloutput.html but the problem is
coming out again and menu bar click is not working again You can see in problem.gif, we can not be able to see sub menu at menu bar,
Normally, we should see the sub menu bar like correct.gif attached

So now I suspect the issue at my curl() function and the syntax
$file_url=my_curl($url,"" , 7, TRUE,2,"");
$dom = new DOMDocument();
@$dom->loadHTML($file_url);
$temp=$dom->saveHTML();

Is it because my php program generating special character into html output so make the click is not working.
And if run the curloutput.html at C: drive in PC in Firefox will igore those special charater so it doesn't have such click issue, Is it True ?
I guess it is related to the extracting process issue or coding from curl(), but don't know to how to proceed,

Any hit or suggestion ? Please review the fillowing php.program of "curlex.php"

Wow, I haven't seen this kind of thing in years. It looks like you have fallen victim to Suhosin:
http://www.hardened-php.net/

While it is called a "security" patch, it is not necessary if you follow generally accepted programming practices, and it creates havoc with all kinds of essential activities in PHP. Got a form with a lot of fields? Suhosin will silently discard any that it thinks are "excessive." Did you think you could have up to 1024 bytes in a GET request string? Suhosin will truncate it. Thought you had safe_mode off? Ha! While not technically a virus, because it will not replicate itself, it still causes enormous amounts of unnecessary trouble. You will note that the last advisory is more than four years old, which is a lifetime in modern IT technologies.
http://www.hardened-php.net/advisories.15.html

You might want to get rid of that thing right now!

You mean Suhosin is out-date thing ?

I save my curl output for $url="http://help.dottoro.com/ljrmdnar.php" into a file of my dottoro.html
in firefox. And Firebug will report the 101 line javascript error in its js script link

Let me try this once again: Who is your hosting company?

Regarding this, I am sorry but I have not got any clue.

javascript error
on line 105, Tree.active.Tree is undefined from FireBug in firefox when one of menu icon is clicked.

I do not think that JavaScript is your problem here.

Author: duncanb7 replied at 2024-11-21 02:10:22

I save source code from phpinfo.php into myphpinfo.html in browser

Please review those setting whether something setting limit to cause the issue

Who is your hosting company?

Please install this script (shown here in its entirety) and give us a link to it. You can take it down later.

Thanks, ~Ray

report_zend_debug On On
safe_mode Off Off
safe_mode_exec_dir /usr/local/php/bin /usr/local/php/bin
safe_mode_gid Off Off
safe_mode_include_dir no value no value

As I said before in other thread in EE, the safe mode is already turn off.

So what other php setting will affect the result , please advise

Expert: Ray Paseur replied at 2024-11-20 06:39:06

Who is your hosting company? Contact them and tell them to turn off safe_mode for your account. If they refuse, get a new hosting company. It really is that simple and there is no good alternative to having a competent host!

Author: duncanb7 replied at 2024-11-20 06:30:03

Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in curlee2.php on line 42

I got the similar warning So. it is same issue as other thread I made in EE

Author: duncanb7 replied at 2024-11-20 06:26:39

Get back the html code for purpose to control its body width and height in iframe.
we can NOT access DOM document for remote site if host and remote is not at the same domain

Why you can do that but I can't probably it is same issue for my hosting company as the other thread
issue I address yesterday

250 points EXCELLENT

I read this question at the time it was posted and I could not really understand the issue. Then I got a neglected question alert so I guess nobody else understood it, either!

I do not understand the steps you are taking with these lines. Why are those in there?

$dom = new DOMDocument();
@$dom->loadHTML($file_url);
$temp=$dom->saveHTML();

However I am absolutely certain that you do not want the @ on the loadHTML() method call. At this point in the application lifecycle you need to see all the Notices, Warnings and Error messages.

Set error_reporting(E_ALL) at the top of all your scripts, and remove the error conditions as they arise.

Using the script below, I am able to read the page at URL http://help.dottoro.com/ljrmdnar.php
See: http://www.laprbass.com/RAY_temp_duncanb7.php

But I do not understand what you want to do with the HTML string that you get back.
