Identifying Non-Supported Characters In A TTF File With GD?
I've managed to get GD working (mostly anyway) on my site - and am utilising the "imagettftext" function.
I am using this function to display individual characters on my website - with a nominated Font.
However, sometimes the characters in my StringText are not supported by the particular font that I am using ...
Directly from http://www.php.net/manual/en/function.imagettftext.php
imagettftext - "If a character is used in the string which is not supported by the font, a hollow rectangle will replace the character."
Can anyone suggest some code that would:
1) compare/look at the StringText supplied within the "imagettftext" function (in my case the StringText will comprise of a single character only)
2) where the supplied StringText (ie character) is NOT supported by the font, then I need for that character to be reported as not supported. ie. either; return a flag or skip the non-supported character entirely - rather than displaying the standard "hollow rectangle".

Form, Type=file And Identifying By Isset()
Windows XP PHP 4.4.2 Apache 2.2 Register_Globals = Off Safe_Mode = On ----------------------- Hi All, I am having a problem getting a file browse input field to be recognized on the next page. Let me show you... page1.php Contains a web form with a file input to attach a file using a browse button. <form method='POST' action='page2.php' enctype='multipart/form-data'> <input name='uploadFile1' type='file' id=uploadFile1'> page2.php contains a validator to check the input and perform an action based on whether or not the browse input field has been populated. // IF THE POST CONTAINS A FILE UPLOAD, PROCESS SECTION 1 IF NOT PROCESS SECTION 2. if (isset($_POST['uploadFile1'])) { echo "File is attached so print this."; } if (!isset($_POST['uploadFile1'])) { echo "File is NOT attached so print this."; } If the user uses the browse button on the form page to populate the field with a file path to a file on his pc, then I expect to see the "File is attached message". However, regardless of whether someone does or does not browse a file, the message is always that they have NOT browsed a file and the variable "uploadFile1" is effectively left unpopulated. OUTPUT File is NOT attached so print this. Conversley, I thought I might be able to use the _FILES variable instead of _POST, but I get the exact opposite, that the browse field is populated all the time whether or not someone has browsed a file or left the browse field blank. if (isset($_FILES['uploadFile1'])) { echo "File is attached so print this."; } if (!isset($_FILES['uploadFile1'])) { OUTPUT File is attached so print this. So, I am missing something. Can someone give me some direction so that I can simply identify (with register_globals = Off) whether or not an input field (input type=file) has been populated or left blank? Is this even possible? What am I missing?

Is ClibPDF Still Supported?
I've used ClibPDF for years from C, and recently attempted to visit their website, www.fastio.com, to see if there were any new features available. The domain still exists, but the website doesn't seem to. Searching on ClibPDF turns up a bunch of messages to comp.lang.php, so I assume somebody built a PHP wrapper for this library and that it was in some kind of general use among PHP developers. Does anybody here know the current state of the ClibPDF library, its developer and the PHP wrapper? Has it been superseded by something better, or is the last version (2.02?) considered good enough and bug free enough that it's just being used as is (was)? Or has FastIO simply folded and orphaned this package?

[ ] Operator Not Supported For Strings
I am trying to define an array in my selection results, assigning each field a row number after the data, such as: data[1], data[2], etc., but when I have a field of type 'char' in the array, I get this message: "Fatal error: [ ] operator not supported for strings".

Is StdClass Officially Supported By PHP ?
It can be very usefull to code: $obj = new stdClass; Unfortunately the few that the documentation officially tells about this class is: ****************************** The name stdClass is used internally by Zend and is reserved. You cannot have a class named stdClass in PHP. http://www.php.net/manual/en/language.oop.php ****************************** It seems that some Pear packages instanciate this class. But should we do the same for code intended for public releases?

PHP 4.0.5 - Function X Not Supported In This Build?
Our host servers' recently updated from PHP 404 to PHP 405, since that update, I've started getting an unsupported function error on one of the servers, but not the other. In this case it's the "getmxrr()" function. I get an 'unsupported' error, which claims that the function, is not supported in this 'build'. Since we work a number of domains, on several different servers, I'm wondering what the deal is.. the use of the getmxrr() function works on 1 server, but not the other, and both of the servers is running 4.0.5 So, I'm wondering, does this error mean : 1) PHP 4.0.5 does not support GetMXRR() any longer? 2) When the host compiled php 4.0.5 on the one server, they omitted the getmxrr() function from their build? IMHO I'm thinking that "2" is what the deal is.. However, it's worth noting, that when I poll that server for installed extensions, it indicates the getmxrr() is available.

Imagettftext() Is Not Working Though It's Supported,
I have created an awesome CAPTCHA, however my CAPTCHA does not work in my web host. I have tested several times and I have found out the reason. The reason is the function imagettftext(). When I replaced imagettftext() function with imagestring(), all worked fine. I would like to know is there any way to make imagettftext() working? My host is using GD 2 or higher with all image types allowed, also freetype libraries and everything allowed. Can't understand why doesn't imagettftext() work for them. I couldn't even find that function from the disabled functions list. imagestring() is ok all the way, except it does not have font and angle support. My CAPTCHA uses 5 different fonts randomly and have some angle with the characters so I really need this function to work!

Identifying An Image
Ive got a tracking system which tracks how many times a user clicks on an advert on my site. At the moment all the listings are set as one so when a user clicks on that advert it gets one click. However, one of the adverts is now going to contain two images advertising two separate companies. Ive set it up so the images and urls are different and they go to their own websites and in my tracking table i have just added an extra column called image and the number 1 goes in if image 1 is clicked on or 2 if image 2 is clicked on. However, to display this is the bit im not sure about. At the moment its displayed in a table like this: Advert Name Category Number of clicks Advert 1 Shopping 257 However, if advert 1 has two images, meaning two separate companies, how can I show this in the above table?

Identifying Dynamic Form Fields
User goes to page which is a form that asks for some basic info regarding returning products for credit/exchange, and also asks for how many products are going to be returned. Upon submitting, a return authorization form is presented to them with the specified number of product fields. I now want to take the input from this form and email it to myself, as well as, display a confirmation page to the user. The problem I have is a can't say, for instance, echo "$field_name"; because field_name will get created dynamically after the user specifies how many products to return. For example, say the user says 5 products, this will generate a form with field names like: return_code0 inv_num0 qty0 product0 cre_exch0 stockout0 return_code1 inv_num1 qty1 product1 cre_exch1 stockout1 return_code2 inv_num2 qty2 product2 cre_exch2 stockout2 and so on.... These get created with a for() loop. Once this form is submitted, how can I address the field names? Code:

Identifying Opening Link For Database Query?
I've got a tricky problem i need to solve, i'm building a banner exchange type site in which there are already about 100 banners so i've had to code things around what already exists to a certain extent. Now each of the banners that go out on other sites have a link on the banner which pops open a window with details of the banner. this would be fine if all my banners were gifs and jpgs but there are also swf and dcr banners so i have no real control over the actual link on the banner. up until now each banner had a html page made for it so when you clicked on a banner it would open a page banner_1.html which had the details of that banner. for obvious reasons i'm going to replace all these redundant pages and put a htaccess redirect at their url to all redirect to a common page popup.php so all details will be dealt with in one file. ok this is fine but my problem is in this page popup.php i need to identify the link that just opened the window so that i can then get the info from the database to put on the page.. remember i can't use the url like so... bannerpage.php?thisbanner=1 but all existing links have unique addresses, is there a way to do this, i'm pretty sure there must be but i can't get my head around it?

Identifying User's Pick From Selection List
I have an application that uses PHP to access a MySQL table and extract rows which match the user's search entry. Data from the matching rows are loaded into an HTML selection list, and the user can scan the list and highlight a selected item. My question: In PHP, what is the syntax for identifying which row is highlighted? My goal is to pass the unique row ID of the selected item to a subsequent form where all the fields will be displayed for the user to edit. I already have the code that loads the selection list and the code that displays the fields. I just need to know how to determine the highlighted item. I have two PHP books, and both discuss loading the selection list, but there is no mention of what to do next.

Identifying Different Unicode/utf-8 Types Inside A Text String
I am dealing with a script that reverses a string that is in hebrew, so I can display it properly when I write that string onto an image, however sometimes the string might be half hebrew half english, so I need a way to identify what language is in the string and only reverse the hebrew parts. in technical terms the hebrew text is encoded in utf-8, and the english text will be encoded in the normal encoding for english, (anscii, latin-swedish whatever, i dont know the name of that encoding) so the simple question is how do I identify different types of encoding within a string? that way I can break up the parts that i identify as being utf-8 and reverse only those (yes I am well aware of methods to display hebrew properly in php, but when writing to an image this is another story, only method i found so far is reversing the hebew text string)

I have tried both of the following attacks on the problem to no avail. First I tried setting the set_on_import directly... then I tried to set all the javascript in a function and then call the function on load... both of them generate illegal characters in the stream. Both of these examples are in a for each that contain a $counter: $js = 'this.getField("moveinready.' . $counter . '").display = display.visible;' . ""; $js .= 'this.getField("moveinready.' . $counter . '").display = display.visible;' . ""; fdf_set_on_import_javascript($fdf,$js,true) and ..........

Parsing Out A File Using Special Characters
I am creating a site where someone would enter data into a few text boxes, with the potential for them to be fairly long. I am therefore saving them into a text file instead of a database. With these, there is a potential for someone to use the enter key in these boxes, therefore making it very difficult to just parse it out by line. I am currently trying to figure out how to parse it by special characters (or groups of characters such as "%%$$%%" or something that noone would ever type, on purpose or by accident) I was wondering if there was a way to parse this out by these special characters, or if there was a way to save those line returns that the people enter as something other than a line return.
