Php - Restrict File Types For A User In A Web Browser?
Nov 29, 2010
i have a question that is almost like other questions but with a small but very important difference. how can i restrict file types for user with a popup showed in the browser.
The standard file input of html can limit that with a command but it does not work in all browser so it is not an option. I do not want to validate the file extension after the user has chosen a file but before that, when he is choosing.[URL].. but it uploads the file after the user has chosen it, i do not want to do that, i want to upload it after the user submits the form.
So the problem looks like this that there are some ways of not letting the user send a not valid file but they are not good because, one is that i validate after the user have chosen the file and the other is that i upload the file before the user submits the form.
I just want a simple thing to not letting to "chose" a not valid file, it does not matter if it will be made with java script or flash, just let it work.
I have looked around for this and haven't found a way that clearly explains how to do this. More often than not the button will close the browser window in one but not another browser.
Is the a simple way of closing a browser window in all types of browser ( Or mainly Firefox, IE and safari on both Mac and PC ) with actionscript?

I need to learn how to create a text duplication effect. As the user is typing a question, the text is displayed simultaneously in another dynamic text box on the page.
I'm creating simple input text field. There's a whole lot of other things going on, but basically the text field is working fine - except for one strange thing: the cursor does not advance as the user types. The result is that as the user types different characters they just stack up on top of each other. The characters don't overwrite one another, but rather just stack up in the space for the first character. Here's the part of my code that defines the text field:
Code: Select allpublic function makeTextField():void{ var myFont:Font = new BankGothicMed(); var myTextFieldFormat:TextFormat = new TextFormat();
I'm working in CS4 but the flash file I'm updating is a few years old - so I'm still working in AS2 for this project.I am working on updating a file that uses combo boxes but am not terribly familiar with how to control them using action script. I have made my combo box editable so that the user can input text. I have several scenes in my flash file that act as different pages. Right now, with the combo Box editable, if the user inputs text and leaves that "page", then comes back to it later, the text they input is gone and the combo box value is blank.Is there a code I can apply to my combo box or scene to tell it to keep the value that the user types in, even if they leave that scene and come back to it later?
I have a page that uses an altered version of kirupas if/else password tutorial, to make my website skip to a frame according to which password the user types in. I have used this code:
I am new at flash and am trying to create a input text box message that goes away when the user types. Here is an example of what I want to do: [URL] On the bottom right hand corner when you click on the input box, the message goes away. Is it possible to do this in flash?
I would like to restrict user input to numbers only between letters. for example: the user is allowed to input "a2b", but "2ab" or "ab2" isn't allowed.
I have input text box. the user can place there answer to question 1 in the textbox. what is the capital of the united Kingdom.the answer is london. so i want a to be able to check the user has subbmitted and typed letters london as there answer. i want to check in iput textbox ( the letter keys "london")
I need to have a search box, and when the user types in a term and hits submit, I want it to go to a URL and add "srch=<whatever is typed in the box>" to the URL address. In other words, if you type in "Cattle dog" as your search term, I want the URL to read "http:[url]..... This should be so easy. I have a TextInput box called "search_txt" and a submit button called "submit_txt".
How do i get the font to change when the user types encode in the Input box then presses enter and then it changes the font in the Output box (which is dynamic) and also embed the font in the output box. So when they type inteh input box the font changes in the Output box.
On (keyPress ("Enter") { if (_parent.Input.text == "encode") { tf = new TextFormat();
Does anyone know of a way to restrict a user from entering a number over 100 into a textinput field in flex? i.e. a user can enter any number between and including 0-100 but not 101
I am working on an application in which i have put one Multi line input text box. I want to allow user to enter data only up to 8 Lines. User can not enter more than 8 lines. So is there any solutions..??? I dont want to use MaxChars as it can restrict user to not enter more than predefined number of characters. I want to restrict user from entering more than predefined number of lines.
Trying to detect a browser close event and send some data to the database when the user closes the browser window...but can't seem to get it to work.[code]
I have need to restrict user input. TextInput should restrict all special characters and punctuation. Any other characters are allowed. In java there is a regex patter:
Code: public function foo(bar1:int, bar2:uint, bar3:String, bar4:Boolean):void{}
What I want is to have the different types of data represented by custom named types which are essentially representing the original data types. I other word, I would like to proxy the data types and have a valid function as following:
Code: public function foo(bar1:PAR_Bar1, bar2:PAR_Bar2, bar3:PAR_Bar3, bar4:PAR_Bar4):void{}
so PAR_Bar1 would proxy the `int` data type, PAR_Bar2 would proxy the `uint` data type, so on and so forth.
The reason I need this is because I'm using a debugger with a GUI that can run methods and allows changing function parameter values in real-time, the issue is that the debugger can't tell me what parameter I'm changing, it only displays the data type of a parameter. So if I need to change 10 different parameters all of type int, the debuggers display all of them as int and not by their names.
I think that if I use proxy types I can easily differentiate between parameters.
So, my question: Is it possible to proxy data types? I mean map specific data types to custom data types that would represent the base data types?
I know how to load in .jpg and .swf files via XML, but the issue in which I want to cover is to have the two alternate. See what I'm going is I'm going to have a quote show up (animated in SWF) then once that finishes, it fades into a JPG. That will in turn fade back to another SWF and then the cycle continues. These will be loaded randomly, but I would like it if I were able to keep it in that order of random swf, then random image, then random SWF and back again.
I am trying to publish a flash file onto a website but once I post it there it keeps looping. How do I get it so that it doesn't loop? I have a feeling it's a setting in Flash that I have to find before I publish it but I don't know where it would be or if there even is one.
In a plugin context (a swf loaded by an another swf), is there any way to restrict access to file system and network in the same time to the loaded swf?Compiler option "-use-network=true|false" does not fit because you cannot restrict both file/network.[code]The loaded swf is in user's document folder, outside Air app folder. Currently, the loaded swf is abble to load "c:/Windows/regedit.exe" and I don't want it (neither sending informations on the network).
Does any one have a working fla. and php script to upload multiple files (with the specified max sizes, and file types) to a server? In addition, when there is an image being uploaded, it would be luxurious to have a thumbnail of the image being uploaded displayed.There is clearly not a simple issue. Scores of designers and developers encountered problems and headaches trying to upload multiple files with and image display (if an image is being uploaded). Even my web designer has a slight problem, although he tweaked some of the code to get a simple upload. Adobe needs to address this issue because it seems that sscores of designers and developers are having difficulty with uploading multitple files.
It is possible to make file transfer from air application via server?I think need to create like byte array streaming or somethink like this from sender and write the destination file on receiver user pc.
I have been updating my flash pages, and so many people cant see the changes, because they have to reset their cache in the browser .. which is fine for any savvy internet user .. but there's a lot o folks out there who dont recognise this action .. are there any tips to talk to the browser that changes have been made?
