Why does the Fatal error appear: Cannot redeclare exc_post () when if ($ _SESSION ['filter1'] == '')?
0
I am writing a tag filtering plugin for wordpress but for some reason I get an error
Fatal error: Cannot redeclare exc_post () (previously declared C: xampp htdocs wor wp-content plugins GOG11 GOG11.php: 64) in C: xampp htdocs wor wp-content plugins GOG11 GOG11.php on line 141
On line
if ($ _SESSION ['filter2'] == '') {
And the most curious thing is that on the exact same line only
if ($ _SESSION ['filter1'] == '') {
There are no errors
And it only occurs when
['filter2'] == ''
for all other values, everything works fine
If, instead of skipping, I indicate 1, then the error appears already on filter4 jumping filter3
Here is the entire plugin code.

you havefunction exc_post(...in the file above six times, you cant reuse the same function name.

In particular if the flags overlap. Try to clean up the spaghetti code, and abstract the function if it only differs ever so slightly.

you havefunction exc_post(...in the file above six times, you cant reuse the same function name.

In particular if the flags overlap. Try to clean up the spaghetti code, and abstract the function if it only differs ever so slightly.

If that's your simplified version, I don't want to know how the original version looked like. Nevertheless - the whole problem is, that you defined the function exc_post two times - one time for each filter, but each time exactly the same way. An easy solution would be to rename the functions for the first filter to exc_post1 and the other to exc_post2.
That would work, but still isn't a good solution, as the main part of your logic is duplicated 6 times. So each time you change your function, you have to change 6 places instead of one, which is a very bad practice.
It would be better to define the filter function one generic time and reuse them, as only the filename changes and everything else is the same.
function exc_post($filter, $file) {
if ($filter->is_category || ($filter->is_home || ($filter->is_feed) || ($filter->is_tag)))
{
$dir = plugin_dir_url( __FILE__ );
$content = file_get_contents( $dir . $file);
$terms = explode (",", $content);
$filter->set('tax_query', array(
array(
'taxonomy' => 'post_tag',
'field' => 'slug',
'terms' => $terms,
'operator' => 'NOT IN'
)
));
}
return $filter;
}
if ($_SESSION['filter1'] == '') {
$file = 'filter1/level_1.txt';
} else if ($_SESSION['filter1'] == 1) {
$file = 'filter1/level_1.txt';
} else if ($_SESSION['filter1'] == 2) {
$file = 'filter1/level_2.txt';
}
add_filter('pre_get_posts', function($filter) use ($file) {
return exc_post($filter, $file);
}, 0);
if ($_SESSION['filter2'] == 1){
$file = 'filter2/level_1.txt';
} else if ($_SESSION['filter2'] == 2){
$file = 'filter2/level_1.txt';
} else if ($_SESSION['filter2'] == ''){
$file = 'filter2/level_2.txt';

Yes. That would be a great solution. Only it gives me an error Warning: Illegal offset type in isset or empty in C:xampphtdocsworwp-includesclass-wp-hook.php on line 75 Warning: Illegal offset type in C:xampphtdocsworwp-includesclass-wp-hook.php on line 77 Warning: Illegal offset type in isset or empty in C:xampphtdocsworwp-includesclass-wp-hook.php on line 75 Warning: Illegal offset type in C:xampphtdocsworwp-includesclass-wp-hook.php on line 77

I think I was able to change it slightly, but it only applies to either filter1 or filter2 is there a way to apply filters at the same time
add_filter('pre_get_posts',function($filter) use ($file) { return My_filter_post($filter, $file); });– zeni1agent

In particular if the flags overlap. Try to clean up the spaghetti code, and abstract the function if it only differs ever so slightly.
