php - Why in some files require /app/ works, in others doesn't? -

-

Some files require '/ app /' to work, in some, But do not need 'AAP /' works on pages where '/ app /' breaks like this? I can not use the __DIR __ , because it can not load css files.

This is because there are 2 types of Unix Path:

Full Path: / app / (always starts with / )

relative path: app / (relative to that place

Imagine you are in the You use / app / (abosolute) - you talk about the / app / folder

if you click the app / (where you are Are related to there) - You talk about / var / www / app / . This means that you want to use the directory "app" in the / var / www / directory.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

javascript - What is an alternative to using getElementByClass for hiding multiple elements? -

-
I have a page with some links that I would like to be able to toggle with two buttons. It works with a link using getElementById, but I need to toggle some of those groups. I started with it, but it failed to work. I've heard that GetElementByClass has worked with everything but IE, but I'm using Opera 11.5 and it still does not work. I've searched a bit, but I'm new to some JavaScript and most of the explanation is not understood. Does anyone help me with a simple option, or can I help me fix the problem I've made? This is a test page I was using. & lt; Head & gt; & Lt; Script type = "text / javascript" & gt; Function hideNames () {document.getElementByClass ("WebName"). Style.display = "none"; } Function ShowName () {document.getElementByClass ("WebName"). Style.display = "inline"; } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; P class = "web...

c - Selecting a file randomly from a file system -

-
This question is related. I need to work on files and directories randomly as a file logic, such as rename, write, read etc. What I was planning to do, was to list all the files and directories along with their paths randomly to choose from this list. But, as the files and directories are created and destroyed in the actual file system, the list should also be updated. I am able to update the list and keep it inadequate in this way and it should also be atom so that the operation can not access any file later that was removed from the previous operation. Can you suggest that there is a different way of choosing files..to somehow integrate it with the file system ... but how do we know about the files? Thanks I'm Michael J. Barber's answer has found something particularly interesting, but due to my dragon ignorance I can not follow it completely You do not want to try to keep a list of files, when the file system is ok you should be able to correct it from C.
