PHP - Basic Rundown Of Using Php

I would like to keep all my classes in a folder placed within the htdocs folder where my php script runs.  Let's say the classes folder is com\jimslounge\classes.  From my script can I instantiate a class like this
$myClass = new com\jimslounge\classes\Jimsclass();  Does it work something like that?  I would hate to have to use include to access classes.

Hello,

Im from the Netherlands and i have a little question about php.

I have a form in php where administrators can make new users. They can fill in a name, password, age and can select a role. The role is a dropdown menu where they can select athlete, researcher and trainer. My problem is that when they select a role, i want that selected role transfert to a php variable. I want to use the variable in a if statment, when sporter selected a new dropdown appears with options like tennis, hockey....

I have seen a lot on google about this with jquery and stuff, but i cant find a good example.

Can u help me?

Thanks.

<?php

This php code is in a file called test.php and is on my drive Letter O in a sub directory called my old photos . I'm having a problems referencing the include back to the the path of where ASEngine/As.php which is on c drive . I have tried all different relative and absolute paths . Any help would be appreciated

Thank You

Does it matter where you start your session at? Does it have to be before the <!doctype> tag or can it go anywhere in the page?

I am quite new to php and the mvc setup, I am developing a library app however starting at the very basics so as not to become overwhelmed!   I am trying to do a basic insert to my book table, this is the code I have so far alsong with the error I am presented with.   Model (models > adminarea_model.php)   adminarea_model.php  

public function create($title_text)
    {
        $title_text = strip_tags($title_text);


        $sql = "INSERT INTO book (title) VALUES (:title)";
        $query = $this->db->prepare($sql);
        $query->execute(array(':title' => $title_text));


        $count =  $query->rowCount();
        if ($count == 1) {
            return true;
        } else {
            $_SESSION["feedback_negative"][] = FEEDBACK_NOTE_CREATION_FAILED;
        }
        return false;
    }

is it okay to name a column "date" in a table ??? just want to know whether this could mess up everything

thanks in advance

This is what I want:   If comparisonTimeH isn't zero, I want it to check if comparisonTimeH is zero, and comparisonTimeM is larger than or equal to 2. If so, I want it to pass and run the script.       This is what I have, and it's not right. It runs the else statement, echo test 2.

    if ($comparisonTimeH != 0 || $comparisonTimeH = 0 AND $comparisonTimeM >= 1) {
        echo "test";
    }
    
    else {
        echo "test2";
    }

    echo "<br />" . $comparisonTimeH . " " . $comparisonTimeM;

My last echo, the one outside of the if statements - it returns 0 and 12. Thus, both conditions that I'm trying to get, are true. My if's logic is clearly wrong, and I can't figure out what operators to use. If I change the AND to &&, it breaks and my final echo doesn't return comparisonTimeH (it's blank).   Please teach me, thanks!

I'm working with the youtube API and the function Code: [Select]
$relatedVideo->watchURL returns a video url

However when I use Code: [Select]
preg_replace("youtube","test",$relatedVideo->watchURL); it gives me the following error
Code: [Select]
preg_replace() [<a href='function.preg-replace'>function.preg-replace</a>]: Delimiter must not be alphanumeric or backslash in <b>C:\wamp\www\site\test.php</b> on line <b>317
Help please?

I'm working with a payment module for a zencart template. The files are in PHP and I know some HMTL over the years, but never touched PHP coding.   Here are three lines of text in my PHP....

define('MODULE_PAYMENT_DOLLARS_TEXT_TITLE', 'Pay with dollars!');
define('MODULE_PAYMENT_PAYPALWPP_MARK_BUTTON_TXT', 'Checkout with PayPal.');
define('MODULE_PAYMENT_PAYPALEC_MARK_BUTTON_IMG', 'https://www.paypalobjects.com/en_US/i/logo/PayPal_mark_37x23.gif');

The picture (in the imgur link) pretty much describes what I'm trying to do. As it stands, it would take too long to simply do everything manually with html and css (both of which I'm pretty good at I think), moving all img src and dates from one div tag to another whenever I wanna add something. So yeah, what's the most efficient way to simply submit a picture, and all my other pictures will move?

I know some of you guys will say to just learn php, but quite frankly, I don't have the time... and all the php books are ~1000pgs long which seems really daunting. I know, my problem's pretty basic and it'll probably be covered in the first 100pages or so, but still, like I said I don't have that much time for the moment.

When I do, however, can you guys recommend me the quickest guide/video series/book to learn practical php? Not the most comprehensive, as the stuff I'm going to be doing's not that complex.

One last thing, I've been hearing about CakePHP; what is it? I read that it's an "open source web application framework", but I still have little clue. I'm currently using dreamweaver for all my web stuff (no I do not use the WYSIWYG feature, I just grown accustom to using it). Should I "learn cakephp"?


Please answer any one of those questions (particularly the first one). Many thanks and I'll be sure to reply!

Hi, I'm very new to PHP so I hope this is not frustrating. I'm having trouble understanding how "isset" works. I'm trying to get it so that when I click a button, it returns two variables(in an array). This works, but I tried to use "Isset" to detect if a array was created, then alter the variable. It's not working... I'm not too sure where I'm going wrong, could anyone give me some advice? Thanks

<?php 


if(isset($_POST['name']))
{
	$userAnswer = $_POST['name'];
	if(isset($_SESSION['test'])){
			$_SESSION['test'][$userAnswer]['var1']++;
			$test = $_SESSION['test'][$userAnswer];
			foreach ($test as $key){
					echo json_encode($key);
						};
					}
	
	else {
	$test = $_SESSION['test'][$userAnswer]=array("var1" => 1, "var2" => 2);
	
	foreach ($test as $key){
				echo json_encode($key);
				};
	}
}


?>

$(document).ready(function(){
  $("button").click(function(){

                var test = "here";
                $.ajax({
				     url: 'info.php', 
				     type: "POST",
				     dataType:'json', 
				      data: ({name: test}),
				     success: function(data){
				     	     
					 $("#click").fadeOut(function() {
					 		 $(this).append(data);
					 		 
					 }).fadeIn();
					
				     }
				 
					});
  });
  
});

Hello there. Well this problem maybe basic but is kind of annoying me. I havea solution to it which I wil lexplain.

I have created a .php document which has html codes as well. It is a form that provides validation, for arguments sake lets say it is a form that validates if a user has entered their username and password, if not it will produce an error.

The problem I am having is I have embedded the code inside the echo
"
code is here
";
Now I have looked at escape characters and tried afew things, yet it still produces the same error on the same line.

Example

   echo

"      
   
   
   !!!!!!!<form action='book.php' method='post' onsubmit="return checkForm('flogin');">!!!!!!
   The reset of the form is here .....
   
   "";
   echo

The area highlighted in exclamation marks is where the area occurs, due to the quotes.


Any suggestions.


Thanks.

Hi everyone,
I'm very new to PHP and have been following Kevin Yank's "How to build a db driven website using php & mysql" 3rd ed. and am working through Chapter 6, where a basic search page is created. What I would like to be able to do is, in the results, display not only the joketext (as done in the book), but also the author's name (which is located in a different table in the db), as well as the date it was submitted (in the same db as joketext), possibly a link to another site and extra info like the joke category. In general, I would like to be able to understand how to adjust the php code to add data related to the results of any given search. The information is already related through the database, how do I use it in the results of a search?

I've used the same names of variables and tables as used in the book.

Thank you in advance for any help you can offer! I really appreciate it.

Below is the code for the part of the code I would like to change (highlighted parts) followed by the code for whole page (2 main sections "search" and "results". In the main code, the excerpt below is located a few lines from the bottom (in "results"):

Note: the only variable currently displaying in the results in $joketext (also highlighted). Ok, enough explaining!

And I'm talking as basic as you can go! I'm trying to implement a commenting system on my website for news articles I post, and I've only gotten as far as creating the script to connect to my database (I use mysql). I've tried every open source script online for this app and I've not been able to get any one to work within my website. They'll work on separate blank html pages, but I can't figure out how to put the code into my existing pages, which is a huge problem.

As a result, I've resorted to creating my own script, which shouldn't be too difficult to make. If anyone could possibly describe a step by step process on how this can be done I would be incredibly grateful! Just note that I don't want to use ajax, jscript or any other languages like that, just PHP.

Another question I have, is how would I organize my database to include all news articles, and comments with a news article "id"? Would I need to put both in separate tables and just assign each comment with the uniqe id associated with whatever news article?

And the last thing, I want pagination for my news. I have it to where if I insert a news article column into my table "mynews", it'll show up on the home page, but how and where would I insert a pagination code to make the articles "paginate"?

I'm using Zebra_Form and I want to populate a select box with some values from a query.  How do I do this?  I have a returnset from MS SQL Server, but I am a newbie and I am baffled about how to frame it into the required array for Zebra_Form. 

The below example from the documentation has a hard coded set of values.  How can I replace this with my queryset ($stmt printed a little further down) instead?

Code: [Select]
// single-option select box
 $obj = &$form->add('select', 'my_select2');
 $obj->add_options(array(
     'v1' => 'Value 1',
     'v2' => 'Value 2',
     'v3' => 'Value 3'
 ));


//sql code here *
$serverName = "serverName\sqlexpress";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password" );
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
     die( print_r( sqlsrv_errors(), true));
}

$sql = "select ticketID, ticketName from tickets order by price desc";
$stmt = sqlsrv_query( $conn, $sql);
