alias of nodejs as node on 14.04

Question

I have a form which is used to insert records into the database and if all goes right redirect the user to the index page with a message (actually set with a session) about the success or failure of the operation.

Now, am able to set the session in add_book.php and display the message in index.php but the message still persist after reloading the page without going away.

in add_book.php. I have this

$_SESSION['insert'] = "Record inserted into the database";
                        session_regenerate_id();
                        session_write_close();
                        echo '...succesfully add new book...';
                        header("Location: index.php");
                        exit();  

and in the index.php, I have this

<?php if(isset($_SESSION['insert'])){
?>
<p class="update"><?php echo $_SESSION['insert'];?></p>
<?php
}//end of isset $_SESSION['insert']
?>

Solution 1

Recently fixed this using nodejs-legacy.

Run the following command:

sudo apt-get install nodejs-legacy

This should fix it.

Solution 2

Well curiously, I have a node. It's an alternatives system symlink and I'm not quite sure how I got it (in a way that you don't). It was a while since I installed it so perhaps I followed this SO post or one like it... Who knows!

You could just write a little bash alias but that'll only work for one user at a time. It might just make more sense to add it as as symlink globally. I'm not sure there's any value going through the alternatives system so we can just plonk one in /usr/local/bin (this is where non-package-managed binaries should go):

sudo ln -s /usr/local/bin/nodejs /usr/bin/node

Edit: That SO post I talked about actually links back to one of ours which might be relevant. It suggests installing nodejs-legacy is the way forward.

Please add the same alias in /etc/profile and restart; after changing any rc file or profile file you must source it.

@Jord i edited /etc/profile with same alias and restarted. But still the problem is same.

Several years late, but... aliases won't (normally) work in a non-interactive shell: stackoverflow.com/a/1615973/7222080 Follow the symlink advice in the answers.

session_start() maybe?

[The Codesee]

Have you tried unsetting the session?

[Patrick Q]

Well, what exactly are you doing to remove the message from the session? It doesn't just go away by itself.

[gbenga wale]

session is started already

[Rotimi]

are you using unset() to remove the session? or perhaps setting it to null?

[gbenga wale]

@patrick I think isset should do the job after it is redirect but after reloading, it should disappear since nothing is set again

[Patrick Q]

Once something is set in a session, it stays until removed or the session is destroyed. It doesn't just go away because you loaded a new page.

[gbenga wale]

@tunde no. didnt do that

[Rotimi]

doesn't @Manikiran solution solve your issue?

[gbenga wale]

@patrick then the unsetting will be inside else statement

[Patrick Q]

You should really go back and review the basics of sessions and if/else logic. You are severely misunderstanding how all this stuff works.

[Rotimi]

you do not need an else statement. Once the insert key exists in the session, echo it then on the next line unset() it. Simple

[srcspider]

Find the location of nodejs via whereis nodejs then do ln -s /usr/bin/nodejs ~/bin/node (yes, no sudo there); replace /usr/bin/nodejs with the path your nodejs is at

[srcspider]

going backwards is not the way forward
