Conditional Operators |
Conditional operators for newbies and professionals. If you do not understand how conditional operators work and the information in the Control Panel is not enough for you, I will try to explain. First, you should believe, that it is very easy! Conditional operators are special codes-symbols, which can perform certain scenarios (scripts). You can create an absolutely new option on your site that is not provided in the Control Panel. First, you must understand and get used to the components of the script code. They are: <?if($code$)?> – it is some condition (code), which points to the operator whom and what we are dealing with. We can mentally replace it by the phrase «If there is»; <?else?> – it is the operator which will do what you say if the condition corresponds to the indicated ones. Replace it mentally by the phrase «If not»; <?endif?> – it is the end of the conditional operator, replace it mentally by «The end»;
Now let’s examine an easy example from the Control Panel: (from Page Editor) <?if($USER_LOGGED_IN$)?> Hello, $USERNAME$ <?else?> You are a GUEST. Please, register. <?endif?> In our language it means: «If there is an authorized user, then «Hello, his/her login!», if not, «Hello, guest!» and the end.» Now the details. What did we use? We said to <?if($code$)?> operator that our script is intended for saying hello to authorized users. We put the following code instead of $code$ - $USER_LOGGED_IN$ , i.e. we said «If there is an authorized user - <?if($USER_LOGGED_IN$)?>». Then the information, available only to authorized users, follows. At the same time, we may use conditions if they do not correspond to the indicated ones, in our example it is Guests. Therefore, after the information for registered users we enter the information for guests. We get Now we have just to close it. We can also exclude Guests and display information for registered users only. For this purpose we just do not use «If not». We get the following: <?if($USER_LOGGED_IN$)?> We are glad that you have registered! <?endif?> It means that only those who have logged in will see the phrase «We are glad that you have registered!». Any code, specified as working for a certain module, can be a condition for the work of operators. In our case (Page Editor), the following examples can be used: Login and logout: Days after registration: And so on.
Conditions for a script can be changed by means of additional capabilities, supported by the operators. They are «=», «>», «<» signs. If necessary, the equated conditions are separated by a vertical line. After the sign, you say to the operator to whom the whole script is directed. <?if($code$='condition')?> I can see this <?else?> And here I can see this <?endif?> Or <?if($code$='condition')?> The main thing is that I can see this <?endif?> Example: <?if($USER$='John')?> John, don’t forget to read e-mail every day. <?endif?> It means «If there are usernames and there is John among them (='John'), then this is to be displayed to him…» The same is with groups, names, gender, date etc. <?if($USER$='Mike' or $USER$='Lola')?> Mike and Lola, here is a secret link …. <?endif?> Groups: And so on. However, operators can work in each other. Example: <?if($USER_LOGGED_IN$)?> Hello $USER$! <?if($GROUP_ID$=3 || $GROUP_ID$=4)?> Don’t forget to click on the ads! <?endif?> <?else?> Please, register. <?endif?> The script is the following: «If there are logged-in users, then Hello, if there Administrators and Moderators among them, then add Click on ads, if there are unregistered users, we ask them to register, and the end.»
The main thing is that you must think well how to write a script, what codes to use and whom they will be directed to. You may write anything, uCoz is very flexible! Additional mini-info: I'm not active on the forum anymore. Please contact other forum staff.

Unfortunately, these codes do not work in news entries, load entries, etc.
You also two unnecessary <div> tags in there.

Bio,
Quote (Bio) The code on its own works fine but when I add it to the html source for the news entry it fails if I understood you correctly, you add the provided code, when adding entries. But this code should be changed in the template itself. CP->Design->Design management(templates)->Site news->Page with entry full text and its comments Quote (Gigabyte) Unfortunately, these codes do not work in news entries, load entries, etc. It does work for news entries. If we speak about Site news in particular, I suggest you use several custom fields for adding download links (CP->Site news->Module settings) And then set a condition for users not to be able to view those fields. |
Hi, i am wondering if i can do this with conditional operators
On the forum page, i created a download section. But i want people who have made specific number of posts to be able to access the contents within that page. Here are pictures. I created this http://s661.photobucket.com/albums/uu334/donyusufahmed/?action=view¤t=why.jpg When they click "download," |
This is not something that you do with conditional operators , this can be solved with Auto Transfer from User to Checked group feature that you can edit in your control panel
go to CP ----> Users ---> User Group ---> Users [Auto Transfer] now go to CP ---> Forum ---> Management of forums and sections ---> your board name (Download) ---> Edit icon ---> Forum entries may be read by: ---> Uncheck the Group named Users and then press save. This will make the registered users from your website that are still in the group below 10 post for example not able to acces the board To busy building a passive income online ;)

I just did that but that download section just disappeared.
I want them to be able to see it but not the link in that section unless they have 10 posts |
Heres what its showing now

komsha, This for example.
Code <?if($USER_LOGGED_IN$)?><?if($USER_AVATAR_URL$)?><IMG SRC="$USER_AVATAR_URL$" BORDER="0"><?else?> <IMG SRC="/noavatar.gif" BORDER="0"> <?endif?><?else?>Please, register.<?endif?> donyusufahmed, I will re-check your problem with conditional operators on my site , but i don't think that it will work in forum posts To busy building a passive income online ;)
