I've got two sort of problems, first is that AJAX CRUD doesn't work properly and I don't know why. I've spend all weekend trying to solve that but nothing. The problem is that I can add something to the DB dynamicaly without refreshing website, but I can't delete it and edit and update without refreshing it. Next thing is that sign of my language doesn't show properly.
I've tried to add and still nothing.
Here is my website code
<?php
//demo the issue
require_once('preheader.php'); // <-- this include file MUST go first before any HTML/output
require_once('ajaxCRUD.class.php');
?>
<html>
<head>
<META HTTP-EQUIV="content-type" CONTENT="text/html; charset=iso-8859-2">
<link rel="stylesheet" type="text/css" href="menugora.css" />
<link rel="stylesheet" type="text/css" href="login_success.css" />
</head>
<body>
<div id=menu>
<li> Item </li>
</div>
<?php
$arg = (int)$_GET['menu'];
switch ($arg)
{
case 1:
include('Item.php');
break;
}
?>
</body>
</html>
and here is my item.php
<html>
<META HTTP-EQUIV="content-type" CONTENT="text/html; charset=iso-8859-2">
<link rel="stylesheet" href="format.css" type="text/css">
<body>
<?php
# this one line of code is how you implement the class
$tblCustomer = new ajaxCRUD("Towar","Towar", "Tow_id");
# don't show the primary key in the table
$tblCustomer->omitPrimaryKey();
# my db fields all have prefixes;
# display headers as reasonable titles
$tblCustomer->displayAs("Tow_nazwa", "Nazwa");
$tblCustomer->displayAs("Tow_opis", "Opis");
$tblCustomer->displayAs("Tow_producent", "Producent");
$tblCustomer->displayAs("Tow_nr_czesci", "Numer części");
$tblCustomer->displayAs("Tow_cena", "Cena");
$tblCustomer->displayAs("Tow_ilosc", "Ilość");
$tblCustomer->displayAs("Kat_id", "Numer kategorii");
# add the filter box (above the table)
$tblCustomer->addAjaxFilterBox("Tow_nazwa");
# add validation to certain fields (via jquery in validation.js)
$tblCustomer->modifyFieldWithClass("Tow_nazwa", "Nazwa produktu");
# actually show to the table
$tblCustomer->showTable();
?>
</body>
</html>
also link for ajaxcrud is here http://ajaxcrud.com/
I want to add that db charset is utf8_polish_ci. Thanks for all clues, advice and help generally.
Ajaxcrud does some dynamic requests behind the scenes to the same page url you'r viewing but might not always keep the part after ? intact. Seeing how you're handline the inclusion of item.php try some other way and check out the code of ajaxcrud. I've been working with it on large system and it has few kinks when used in this kind of way.
Also as to the encoding, there are encodings at least in the preheader.php, javascript file, your php.ini, mysql database and webpage itself. All should be set to UTF-8 for convenience.
Ok here is the trick to keep track of your filter. Ajaxcrud creates a bunch of $_SESSIONS variables so 1st load the where clause before using the class:
$_SESSION['ajaxcrud_where_clause']=$WhereClause;
You probably experienced some warning then after calling the display (showtable) add this short sequence..
$tblCustomer->showTable();
if(isset($_SESSION['ajaxcrud_where_clause']))
{
$WhereClause =$_SESSION['ajaxcrud_where_clause'];
}

I am wondering why php does certain things twice, instead of once, when a certain meta tag is in the html portion of the file and the file is browsed by Firefox.
The code is like this:
<? /*...normal php code, including writing record to MySQL...*/
send('dan#example.com',$subject,$body);
?>
<!DOCTYPE html><html>
<!--PROBLEM on next line-->
<META http-equiv=Content-Type content="text/html; charset=utf-8">
<head>
<title><?= $thisPage?></title>
<link href="<?= $cssURL?>css.freedom-and-purpose.css" rel="stylesheet" type="text/css" media="screen, projection" />
<?
include $dataPath . 'data.php';
?>
The result is TWO records written the database and TWO emails sent, whenever the page is called by FIREFOX. IE and Chrome not producing the problem.
There is a lot of other code in the program, but the reason I showed the portion above is that removing the line that starts with
<META...
solves the problem.
That meta tag is in there because one of the packages I run included it in their code sample.
So, what is that meta tag causes php to double do on DB-writes? And same thing on sending email?
Chances are this is actually a request for favicon.ico being caught by your main PHP file. Putting an empty file in favicon.ico or preventing your PHP from handling that URL should do the trick
enter code hereI would suggest you go through your code in some details and check its formatting.
Phil mentioned the meta tag about which I agree with. His suggestion of <meta charset="utf-8"> would be my preference.
Secondly the line sending the email looks odd. Single quotes aren't an option in php for data replacement, so the line send('dan#example.com','$subject','$body); would result in an email with the subject "$subject" and body just "$body".
Additionally send('dan#example.com','$subject','$body); appears to be missing a quote after $body.
I would advise you to move away from short php tags for opening and closing chunks of php <? ?> and get in the habit of <?php for clarity and to ensure the server you're using processes the code correctly.
Finally, I hope include $dataPath . 'data.php'; adds a </head> and a <body> to the html, as you're currently missing those too.
I am trying to make a website in PHP (I don't really have any experience in this). What I did was use an existing website that somebody created for me and just went about changing things in the .php files.
I had this in header.php:
<base href="http://old-domain.com/"; />
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<link rel="stylesheet" type="text/css" href="css/default.css?v=4" />
<link rel="shortcut icon" href="favicon.ico" />
I just changed the 'old-domain' to 'new-domain'.
Now, my homepage of the 'new-domain' looks fine. But all other pages, like new-domain.com/help or new-domain.com/about give me a 404.
On the other hand, when I change the 'new-domain' back to 'old-domain', it displays my old website properly, so I guess this means that the code is alright.
What am I doing wrong? Do I need to set up new-domain.com/help, etc somewhere else?
Thank you.
Just check whether any other file contains the link www.old-domain.com and change it to www.new-domain.com.
I assume the project structure is the same.
because there is no seperate php file for those pages create seperate file for each like help.php and about.php and then include those in header
Maybe its a stupied question but i didnt fild any answer for it,
If i have file with the html tag head tag&meta.. and I include him in all my web page, its effect the seo of the site?
I have file named "start_html.php" that have this code:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="description" content="bla bla.">
<meta name="keywords" content="bla bla">
<meta name="author" content="bla">
<title>bla bla</title>
<!-- CSS: -->
<link href="style.css" rel="stylesheet" type="text/css" media="screen" />
<!-- JavaScript -->
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
I start every page with this line: <?php include('start_html.php'); ?>
When i check for code error on w3c validator its says that i dont have those tags so the page is not coded good.
If the code from that file is not being displayed in your web page then obviously your PHP code is incorrect and that file is not being included. You need to make sure you have error reporting on and displaying all errors as this will catch this for you.
See this StackOverflow question for how to enable error reporting.
You should have these meta and title tags on all your pages, so including them from PHP is certainly not a bad idea.
However, if the W3 validator tells you these tags aren't there, you should check your output. Perhaps start by 'show source code' in your browser, and see if the tags appear there.
If you try to send your source file for validation, where you have:
<?php include('start_html.php'); ?>
Of course you will get the expected result - no tags, because the source file must be parsed and handled by PHP.
You can give a working link for validation, or copy output in your browser after execution, save the file and send it.
Ok, I am having the weirdest problem in history. I am making a website that works perfectly in HTML, but is having some REALLY odd behaviour when rendered from PHP - despite having the EXACT SAME client source code (I literally went through it character by character).
At first I thought I'd messed up something in my 'functions.php' file that I'm including, but I don't get any errors, and when I copy&paste the contents of that file into the place where the include('functions.php'); line is, the problem disappears.
Here's my code (with some HTML removed, this is all of the PHP):
<?php
error_reporting(E_ALL);
ini_set('display_errors','1');
include 'functions.php';
$footer = file_get_contents('footer.txt');
?>

<?php
echo trim(GetNav());

<?php
$NumberOfNewsItems = 2;
echo trim(GetNews($NumberOfNewsItems));
?>
</div>
<?php
echo trim($footer);
?>
</body>
</html>
The functions GetNav and GetNews grab info from the database so I'm not going to show the code from them, plus, as I mentioned earlier, if I don't include the file but instead copy it's contents to the place I make the include call then most of the whitespace disappears (there's still some where the 'echo $footer' call is.
Basically, when you look at the source code, everything looks fine. Where stuff gets incredibly strange is when you hit F12 to look at the dev tools and the elements tab shows a whole bunch of extra whitespace (surrounded by double quotes) immediately after the tag (which impacts the look of the site) as well as between the footer and content Divs (which again, impacts the look of the site).
Also in this view, all of the tags from the are below the first set of white-space and the tag is empty (eg: <head></head>).
The source code looks fine (and if I copy and paste the source code into a HTML file it works flawlessly) and I have to admit that this has me tearing my hair out.
Please help me Obi-Wan-Kenobi, you're my only hope (yes, I love Star Wars, although I wish they'd made more than three movies).
P.S. This might be mega-obvious, but I'm a .Net developer doing this for a family member in my spare time (also it's fun to learn new languages, even ones overly fond of the $ sign), so apologies in advance if I'm the world's biggest newb.
EDIT: What I see in the dev tools is this:
<html xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body>
"
"
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<title>Removed</title>

<link type="text/css" rel="stylesheet" href="css/jquery-ui-custom.css" />
<link type="text/css" rel="stylesheet" href="css/main.css" />
Etc.
EDIT2: Just to be clear, I don't care what the dev tools show, it's just that I'm getting whitespace showing where those quotes are on the actual website, other than that everything is perfect.
EDIT3: Also, the whitespace cannot be clicked on with the element selector and selecting the whitespace in the element tab does not highlight anything on the website. Deleting it in the element tab however DOES fix the website (until it is reloaded obviously), but obviously doesn't help me with my problem.
Try removing the ?> in your functions.php file and no blank rows after the code. And is the functions.php in the same directory as the main file?
And just a tip, include a footer.php instead of file_get_content :-)
I wasn't able to fix this in a way that satisfies me, but here's the workaround that I implemented:
I removed the include from the header entirely and broke up functions.php into one file per function and just included them where they needed to be called.
This alleviated my problem, although it's not ideal. Glad I don't have to use PHP on a daily basis :).
I had the same issue, on the console the source of the html looked like :
By checking the encoding some files were encoded with utf-8 with bom and some with big5. By saving those file to utf-8 ( without bom) solved the issue for me.
I have used Sublime Text 2 with the EncodingHelper from the package manager to see the current file encoding.
Hope it helps.
I am creating my portfolio site and I am wanting to include the head section as a php include on my page. Reason being is because the site will have a fair few pages and I will want to make changes later on to things later on like tidying up the css files.
For example;
<head>
<?php include('head.php'); ?>
</head>
as opposed to all this below being shown on each and every page:
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title></title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width">
<link rel="stylesheet" href="css/normalize.css">
<link rel="stylesheet" href="css/main.css">
<link rel="stylesheet" href="css/1140.css">
<link rel="stylesheet" href="css/ie.css">
<script src="js/vendor/modernizr-2.6.1.min.js"></script>
</head>
I just didn't know if this was good practice to do, as with this being my portfolio site, I need the code to be correct from the start also as they will probably look into the standard of it also.
What are your opinions and advice people? Thanks.
Yep, it's quite standard. But instead of writing:
<head>
<?php include('head.php'); ?>
</head>
you should put the tags inside head.php. I say it's better because what's inside head.php has no sense without the head tags, so they are kinda linked together. It's good practice to join things so linked into a single file without having to repeat open and close head tags for each page.
Actually, it's even good practice (and commonly used) to have header.php, body.php and footer.php files that has respectively:
header.php
<html>
<head>
...
</head>
<body>
body.php
...
footer.php
</body>
</html>
I'm doing that in my application but I've found that it's not a good idea, because you have many of your stylesheets, javascripts, etc in a php file including the head section and you'll have problems with including it in php files in nested folders. this problem is because of relative paths.
If you can use absolute paths then it's ok otherwise it's not a good idea ...
PHP Includes are used like this all the time. Any time that you have content that will be the exact same on every page, it is very helpful to use an include
This is an old topic but I use
<?php include_once("phpinclude/head.txt"); ?>
phpinclude is it's own folder and I keep the footer, header, and common place info in that folder. .js, and .css has it's own as well.
Edit: I use require now. I would rather have a code fail and die rather than give some random string. They are the same except one dies and the other will print out an error or random code. This is for people learning PHP, not old heads.
