First, I would check that the page is actually blank, and not just serving the PHP as HTML.

The next thing I would check is the file permissions.

After that I would take a look at the server log to see if there are any errors reported there.

Next, I would make sure display_errors and error_reporting are turned on and insert an error into the page to make sure it is actually being executed.

Thanks,

display_errors help a lot. I had a parsing error. I wasn't able to see it in nano but when I erased it and re-typed the line, it worked fine.

E-mail tracking in PHP

Hi, I am new to PHP. I am currently working on CRM project, I need to keep track of email status and update into my database such as who read the email or who opened?, who deleted?, who replied? and also When was the email opened/deleted/replied? Date and time. is there any possible to track if someone has read the email or hasn't which I have sent the email to them?

And you are what, writing the mail client then. No mail client will ever sent you a notification upon deletion, reading or reply.

You could try a redirect under each and every link in the e-mail, or possibly the images used in the e-mail. And you could track the hits this redirect page gets. This would give you a somewhat decent overview of how many people open / read. But again delete is a lot harder if not impossible to track.

thanks for your reply, I used images with my message content, I got read status. but I need delete status. First of all I want to know is it possible to track for delete? if yes is there a way to find out if someone delete the email which i have been sent?

If my memory serves IMAP has some features for this but your code has to manage this. If the user can connect to the email via an outside email program, outlook for example, then I do not think you can do anything about it.

You may look at your email server, the actual software that manages the email, and see if it has any kind of user logging features.

try read this in the php manual http://php.net/manual/en/function.imap-delete.php[^]

If your PHP files are related to web sites, you can use a web server that supports PHP. Xampp[^] would be one example; it will interpret the required PHP files on the spot; it can also be used to just compile-and-run a PHP file, as PHP is a general programming language, not necessarily linked to web stuff. You'd have to look the details up in the manual of your PHP system.

hello guys... I have an html page inwhich I collect some data using text boxes. Now in this page, I have button and I set the action attribute of <form> a php script like this

<form action="test.php" method="post">
 -----

Now this does the job. But the problem is that I dont want to be redirected and want to stay on the same page but at the same time want to execute the test.php script. How can I do that? thnx

You can do that with an ajax call.

I.e create an HttpWebRequest object, ask for test.php and then display the results on your (already loaded & displayed) page.

I'll see if I can't fish out some old code I have lying about somewhere.

Perhaps it's your lucky day!

Couldn't find the old code that I had in mind, so quickly hacked something together that should demonstrate the principle for you.
Also helped improve my own code in the process of ensuring that this code would be pretty easy to re-use. The submitForm function is fresh off my neurons and axioms - wish I'd thought of doing that when I last coded in php.

You'll need to download AjaxRequest.js - I've not included it in this post due to it's size. (AjaxRequest[^)
Though everything else you need is here.

Apologies for the total lack of error handling, and the Mickey Mouse test.php. It should however be more than enough to demonstrate my approach. I'd be interested in seeing what devoutees of jQuery think (yeah, I know it's already written, but it's about 18 times the size of code performs the functionality that I need)

Hello, guys! Smile | :)

I am a newbie in web building, but I want to make my personal web site by myself. I want to embed there a php login form, but it is difficult for me to write the correct code. I surfed the internet and found a program that builds any form you want. It is called php forms (http://phpforms.net/). But I don't know whether to try it or not.
Has anybody worked with this software? What would you suggest me to do? Confused | :confused:

What I want is a way to make sure the user has filled in all fields (except the file input field) before sending, to make sure when they press send message, it sends with information on it. Second I want when the user uses the file input to upload a file, it has to be a JPEG with a max size of 5MB. Anyone know how I would do this?

Briefly, you will need to add a scrap of javascript to your page. In your <form ... > add something like
onsubmit="return check_fields()"
Somewhere in your page (I put it in the head section) put something like

<script type="text/javascript">
    function check_fields() {
        if (document.getElementById("xxx").checked || document.getElementById("yyy").checked)
	    return true;
	alert("You must select either xxx or yyy!");
	return false;
}
</script>

The function should return true if it's OK to submit. If there's something wrong, spit out an alert to say what the problem is, and return false so the form won't actually be submitted. Obviously, your checking will be more complex than this example which I ripped out of one of my sites.

Cheers,
Peter

Could you be any more vague? Apache will always list a reason as to why it won't start in the error log. Which WAMP should provide a link to.

The most likely reason is that you are already using the port that Apache wants to use (80) is already binded to another application. An application that blocks this port without telling you is Skype for example.

An XML printer thingy

Hi All -

After shaking my head with the output of xml.Elementry(root).write(fp), which dumps the entire XML tree structure onto one line, I started doing some research. I checked out prettyprint from effbot.org, which sort of inspired me to write the following.. It handles stand alone XML tags and XML tag pairs, attributes, tag text and tag tails. I hope people find it useful...

import xml.etree.ElementTree as xml


def DumpXMLElem(e,deep=0):
    noneg = 0

    # indent the tag according to the depth in the element tree.

    for i in range(0,deep):
        print '   ',

    # find out if the elment has children or a text field, if so
    # this is part of a tag-pair, otherwise it's a single stand-
    # alone tag.

    c = e.getchildren()
    
    # print the beginning of the open tag
    print '<'+e.tag,

    # print the tag attributes within the opening tag
    for i in e.attrib:
        print ' '+i+"="+e.attrib[i],
    
    # if this is a stand-alone tag (no children and no text)
    # print out the proper tag terminator
 
    if(len(c)==0 and e.text==None):
        print '/>',

        # print the tail, if supplied
        if(e.tail):
            print e.tail
        print ' '
        noneg=1    # flag to avoid printing the closing tag
    else:
        # this is part of a tag pair
        print '>',

    # print the tag's text, usually that stuff between the opening and closing tag.
    if(e.text):
        print e.text,
    # if the element has children, end this line and go process the children.
    if(len(c)>0):
        print ' '
        for s in c:
            DumpXMLElem(s,deep+1)
        # back from dealing with the kids, go line-up the ending tag with the 
        # same indent as the opening tag.
        for i in range(0,deep):
            print '   ',
    # print that ending tag, and any tail that the element had...
    if(noneg==0):
        print '</'+e.tag+'>',

You could use the code I posted in one of your above questions about submiting a form to a php file.

You would also probably want to use this function that I hacked together some time ago.

Basically, you can run the php script, then get a callback once it's done. In the call-back you'd just close the window of concern.

function myGetAjaxResponseWithCallback(target, url, callbackFunc)
{
  AjaxRequest.get(
	{
	  'url':url,
	  'onSuccess':function(req){ target.innerHTML=req.responseText; callbackFunc();}
	}
  );
}

I suppose a to use it you'd just
1) define a function named myCloseWindow, or whatever.
2) form the url based from the php script you wish to run, along with any arguments given to it
3) create an element on the page that will serve as a container for any response text returned (or just delete "target.innerHTML=req.responseText;" from the above function)
4) call myGetAjaxResponseWithCallback(target, url, myCloseWindow)

Alternately, you can avoid defining a function myCloseWindow (globally) and can do so thusly:

myGetAjaxResponseWithCallback(target, url, function(){** do whatever you want in here **});

I seem to remember using this method to process results of ajaxRequests as they came back in.
