How to clear cache automatically?

Hello,

In Dolphin 7.1.3, how to clear the cache automatically when the profile page is loaded?

I Wanna clear the cache in Admin panel, under tools option, which has store cache is displayed in pie chart without manually.

Can any one give idea asp.

Thanks in Advance.

So you want to clear all the caches when a profile page is loaded.  If you have a problem with the profile page on load that you think is connected to the cache, list that problem so we may help with a real solution.

ya. You are right.. I have the problem when the profile page is loaded.

I have added a new block in profile page. That the block will works based on condition.

If the condition is satisfied that block will be visible. otherwise it will not visible.

Here only I have the problem when the condition works.

Page blocks have individual caching. Edit the block and make sure the caching is disabled. Set to 0 for that custom block.

I have set 0 for that block. but the same problem occurs again. when I clear the Admin panel DB cache thats will work properly.

 Exactly what is the problem you are experiencing? 

I added new block in profile page and added the new column 'Pid' in 'Profiles' Table in database. and add the below code in profile.php

$iPid = $GLOBALS['MySQL']->getOne("SELECT `Pid` FROM `Profiles` WHERE `ID` = ".$memberID." LIMIT 1");

if($iPid == 0)

{

$sSql = "UPDATE `sys_page_compose` SET `Column`='1' WHERE `Caption` = 'Certifications'";

 $bResult = (int)$GLOBALS['MySQL']->query($sSql);

}

else {

$sSql = "UPDATE `sys_page_compose` SET `Column`='0' WHERE `Caption` = 'Certifications'";

 $bResult = (int)$GLOBALS['MySQL']->query($sSql);

}

Here when the $iPid is '0' the column is SET 1 for that Certification block. Otherwise the column is SET 0.that's why I have to clear the cache in each time when the profile page is loaded.

Ah, now i see.

Your not using a proper method to hide and show a block. That's why your having problems.

Your Certifications block should be a php block. The code to check for this should be in that php block.
 

Reason.. The way php blocks work is they will not be displayed on the page if there is no output. So if you check within the block itself, you can use that check to determine if the content of the block is to be displayed or not.

If you do it this way, it will function properly without the need to clear the cache and there will be far less overhead on the systems resources.

Thanks for the reply deano.

Now I have changed the certification block to php block. But still I have facing the same problem.

Your code in profile.php has to be removed.

As i stated, your php block must handle the checks and only display data when the proper condition is met.

You have to do this properly for it to work.

There is any way to set the block visible for different users like member,guest?

Any solution to split the member - Teacher and Student?

Here I have set 'Pid' is 0 for Teacher and 1 for student.

I wanna to set the Certification block is visible for only who logged as a Teacher.

I will give you some example code. Put this in a php block.


if(getLoggedId() > 0) {
    echo 'Member logged in.';
}


That code will show a block containing the text Member logged in.

The block will only show up for logged in members, but will not be there when a guest views the page. And it will do it properly without having to clear the cache.

Yes. You need to do this.

$iPid = $GLOBALS['MySQL']->getOne("SELECT `Pid` FROM `Profiles` WHERE `ID` = ".$memberID." LIMIT 1");
if($iPid == 0) {
   In this section you put the information you want displayed.
}

What happens is the block will output data only when $iPid == 0. Other wise it does nothing. If the block does not output anything, dolphin will simply not display it.

I have removed that the code in profile.php.

As i stated, your php block must handle the checks and only display data when the proper condition is met.

Do you mean that the condition should be in that block content?

Kindly describe what I do fix this problem..

Actually you will need to check for a logged in member as well. Becuse iPid will always be 0 for a guest based on that code.

So something more like this.

if($memberID > 0) {
   $iPid = $GLOBALS['MySQL']->getOne("SELECT `Pid` FROM `Profiles` WHERE `ID` = ".$memberID." LIMIT 1");
   if($iPid == 0) {
      In this section you put the information you want displayed.
   }
}

I also ready described what has to be done.

Show me the content of your block. I will write the code for you. I guess your not understanding all the samples i am providing.

if(getLoggedId() > 0) {    echo 'Member logged in.';
}

Here also the same problem happens. When I logged as a Member the block is displayed. But if I logged as a guest it is displayed again.

When I clear the cache in Admin panel it will not visible. It doesn't work properly without clear the cache??

ya. This is my code which is written in the Certification block content.

$memberID = getLoggedId();

$iPid = $GLOBALS['MySQL']->getOne("SELECT `Pid` FROM `Profiles` WHERE `ID` = ".$memberID." LIMIT 1");

if($iPid == 0)

{

$sSql = "UPDATE `sys_page_compose` SET `Column`='1' WHERE `Caption` = 'Certifications'";

 $bResult = (int)$GLOBALS['MySQL']->query($sSql);

}

else {

$sSql = "UPDATE `sys_page_compose` SET `Column`='0' WHERE `Caption` = 'Certifications'";

 $bResult = (int)$GLOBALS['MySQL']->query($sSql);

}

echo "<div id='#' style='margin: 10px 10px 0; overflow: hidden;'><button class='bx-btn bx-btn-img' onclick=showPopupAnyHtml('http://localhost/Social-english/m/files/upload');> Upload </button></div>";

Then you have a problem.

That simply is not suppose to happen. You have a caching system problem somewhere.

But i also do not understand how you can clear the cache in admin while testing as a guest.

In any case. You have something wrong with dolphins caching system or a external caching engine.

I put up a test on my site. http://www.deanbassett.com/

And as i suspected, this code.

if(getLoggedId() > 0) {
    echo 'Member logged in.';
}

Works exactly as it is suppose to.

You can join my site and see for yourself that it works.

But i also do not understand how you can clear the cache in admin while testing as a guest.login as a guest in one browser. And login as a Admin in another browser. When I face the cache problem in the guest profile page. I will clear the cache in the Admin panel which is opened in another browser. Then refresh the guest profile page.

That's may be wrong with dolphins caching system or a external caching engine as you told, how can I resolve this?

Deano,

your way is working fine. Thanks a lot.
