Basic PHP assignment

[TrillionBuks]

Good afternoon everyone. I am new to PHP and as a consequence new to this site. I am applying for an internship with a web company and they gave me a sample assignment to complete. They know I do not have any experience with PHP and said they want me to be resourceful and seek out a way of completing the assignment. In addition to the assignment I would like to practice at home in a windows environment. Do you have any recommendations for a free download?

 

The following are the parameters of the assignment I was given:

 

Develop a form that gathers and emails all the info upon submitting it.

 

Form structure:

 

first_name, last_name, email, phone

 

all fields are required

 

validate the email and phone structure

 

Any information is appreciated. Thank you in advance!

The assignment is a very basic one. Easy enough.

 

I am confident that by using this forum's search bar and the one on http://www.google.com, you will find all the information that you need. If you get stuck, come back and ask a question about what's not working.

 

I code in Dreamweaver (not free anymore?) or Notepad (free). A lot of people say that Eclipse (free) with the PHP plugin is teh best PHP editor that they've used.

to create a form, and to process the results: http://www.tizag.com/phpT/forms.php

 

for sending the info in an email: http://us.php.net/mail

 

here is an example: http://php.about.com/od/phpapplications/ss/form_mail.htm

 

you will first create the html form...

 

<form>
<input type="text" name="first_name">......

</form>

 

then you will use php to capture the results and then plug them into the mail function (php.net/mail) to send to wherever.

 

for validation, for email (<input type="text" name="email">):

 

if (document.forms[0].elements["email"].value == "") {
	window.alert("Please enter your email");
	return false;
}

validRegExp = /^[^@]+@[^@]+.[a-z]{2,}$/i;
	strEmail = document.forms[0].email.value;

  // search email text for regular exp matches
if (strEmail.search(validRegExp) == -1) 
{
	alert('A valid email address is required.\nPlease amend and retry');
	return false;
   } 

 

for phone validation:

Upon my initial research I see that PHP makes call to headers and executes the data contained on the page. Is that a correct understanding of the following snippet of code?

 

if (!isset($_REQUEST['email'])) {

    header( "Location: http://www.example.com/feedback.html" );  //verifies if variable has been defined, calls header with some sort of feedback

 

  }

  elseif (empty($email) || empty($message)) {

    header( "Location: http://www.example.com/error.html" ); //if either field is empty call the error.html header and execute instructions within

 

  }

  else {

    mail( "[email protected]", "Feedback Form Results",

      $message, "From: $email" );

    header( "Location: http://www.example.com/thankyou.html" ); //everything checks and execute confirmation from thankyou.html

 

If so, do I need to create dummy headers and instructions to have my code call from them? Do you think I can just make up pertinent names without creating the file to back up the call? How can I test my program in a windows environment? You mentioned notepad with a php plugin; Will that enable me to test my code for syntax errors and logical mistakes?

 

Thanks again!

The header("Location: ...")s don't do anything but redirect the user to a new page. It validates what data the user has sent using an HTML form and depending on that data it gives an appropriate response. (For example, the first one "!isset($_REQUEST['email'])" checks to see if the user has given his/her email address (if the inverse of the value returned by isset($_REQUEST['email']) is true); if the user hasn't, simply take them back to the original form.

 

It sounds like you are from a C (or like) background; note that PHP does not have header files in the context you are using them; header() refers to the http:// header sent to the clients web browser.

start off w/ this, its a pretty simple explanation of using a form and capturing the results w/ php.

I appreciate all the information. A quick question about "validRegExp = /^[^@]+@[^@]+.[a-z]{2,}$/i;" I have never seen code like this before and was wondering if you can explain to me what is going on. I am assuming that it is checking to see if the email string contains valid characters followed by an '@' some more valid characters (a-z) then a period and finally a valid extension. Adain this my assumption and would appreciate a detailed breakdown of it for my knowledge.

 

Thanks again!

can't really offer you a detailed breakdown of it, all i know is, it works, and its javascript. i won't lie, i copy and paste a lot of things that i use, which is something i use. but all you really need to know is this works, just name your input field like: <input type="text" name="email">, then you're good to go for validation the email field. all that /^[^@]+ is regular expression, its better you get to the html form first, then begin worrying about the validation. i would say you would validate last.

[discomatt]

It's not javascript, it's a regular expression (regex)... a very powerful search language. You can find more about it here

 

http://www.regular-expressions.info/

 

If you are going to be using regex on a regular basis, i highly recommend regexbuddy (the program advertised on that site)

 

Also, as a subnote.. i really like the php/mysql/apache installer here:

http://www.wampserver.com/en/

 

And I really like Serge Baranov's build of SciTE for a basic programming environment:

http://amip.tools-for.net/SciTE-CVS.exe

 

Oh, and what you asked... a breakdown of the regex

 

/ - begin regular expression

^ - start of string

followed by

[^@]+ - match any character that is not '@', 1 or more times

followed by

@ - match character '@'

followed by

[^@]+ - match any character that is not '@', 1 or more times

followed by

. - match any character that's not a linebreak... i believe this should be '\.' which is match '.'

followed by

[a-z]{2,} - match a through z, 2 or more times... i believe this should be [a-z.]{2,} which will match a through z or '.' 2 or more times (for .co.uk ect domains)

followed by

$ - end of string/line

/ - end regular expression

i - case insensitive search

First of...thanks Matt for the detailed breakdown.

 

I started writing my first HTML form using the website that was previously given. I have some questions about the following inital attempt at the form:

 

<form method="post" action="mailto:[email protected]">

First Name: <input type="text" size="10" maxlength="40" name="f_name"> <br />

Last Name: <input type="text" size="10" maxlength="40" name="l_name"> <br />

Email: <input type="text" size="10" maxlength="40" name="email"> <br />

 

<input type="submit" value="Send">

</form>

 

As the code is written will it display boxes labled First Name, Last Name and email?

What does the size refer to?

Is maxlength the length of characters it allocates?

Was I correct in changing name= f_name, name= l_name and name=email?

I want to add a box for a telephone number. DO I need to change the input type? If so to what? should I drop maxlength to 10?

 

Thanks.

Well assignment said be resourceful

 

and if ya dunno the language, creating one on yer own is bout the last thing ya wanna do.

 

Next step, look for a generation script (a script that generates the code for a form for u)

 

Contact form Generator

 

u can prolly find other automated generators

 

[soycharliente]

Best email regex I've ever seen:

/^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*(([,]|[,])\s*\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*)*$/

I take it that my HTML form is incorrect. I am trying first to create the form, then add the PHP to it.

Is this the wrong aproach? Is there any help other than a automated script generator that you can offer?

[TrillionBuks]

The following is a form I created that meets the specifications of the assignment. Now that I have the form how do I add the needed PHP code so that I meet the requirements of the assignment. Thanks again.
