I am trying to pass a function into an existing variable to set specific locations within my template. However when I use the function switch I am not receiving any results.
function posicionnavbar($posicion) {
switch ($posicion) {
case 'top':
return 'top';
case 'soc':
return 'soc';
case 'nav':
return 'nav';
case 'usr':
return 'usr';
}
}
And the variable I am attempting to append to.
$omni[posicionnavbar($tabs['position'])] .= $nuevo_tab;
More Info:
$tabs['position']
Is either - top, soc, nav, or usr
$omni***
Is the variable used within my template for each location. IE: $omnitop
I have passed the variable using $omni .= $nuevo_tab; and using $omni within my template to confirm everything was working, with success. Which lead me to something being off with my function.
How can I pass my function into my variable to change the variable name?
end results would output one of the following:
$omnitop .= $nuevo_tab;
$omnisoc .= $nuevo_tab;
$omninav .= $nuevo_tab;
$omniusr .= $nuevo_tab;
I did manage to solve this.
${'omni'.posicionnavbar($tabs['position'])} .= $nuevo_tab;
thanks to PHP Cookbook
Knowing the proper symbols to link the variables together, I got rid of the switch and function altogether. The way I have this set up ${'omni'.$tabs['position']} .= $nuevo_tab; is enough to get the job done.
You can also create an array $omni with keys returned from your function. Then it will be easier to iterate over the results
<?php
function posicionnavbar($posicion) {
switch ($posicion) {
case 'top':
return 'top';
case 'soc':
return 'soc';
case 'nav':
return 'nav';
case 'usr':
return 'usr';
}
}
$tabs['position'] = 'top';
$nuevo_tab = "Something";
$omni[posicionnavbar($tabs['position'])] .= $nuevo_tab;
//let's imagine you got the value of $nuevo_tab here (for simulate the loop)
$omni['soc'] .= "Something related with soc";
$omni['nav'] .= "Something related with nav";
$omni['usr'] .= "Something related with usr";
foreach ($omni as $key => $value) {
echo "\n";
echo "the key {$key} has the value -> {$value}";
}
Anyway, your answer is valid. The one I have proposed is only for convenience. In case in the future you want to access what seem to be variables that are related, with a simple loop
