pages selector empty and unique field values

[Barry]

I'm trying to figure out how to create a selector that will find pages where a certain text field is either empty of unique. I have about 3500 records where the majority of have a specific field which is simply empty, there some records however that will have a certain value filled in this same field and some of these values are the same. I want to only select the first page which is found with this value and exclude the rest of these pages with the same value.

Any ideas?

Was this meant to read empty or unique? You want to select all records whose a certain text field is empty or has unique values?

There isn't a selector option to filter pages by unique value, but you can do something like this

<?php namespace ProcessWire;

$empties = $pages->findMany("template=record, textField=''");
$fulls = $pages->findMany("template=record, textField!=''");
$uniques = new PageArray();
$fieldValues = [];
foreach ($fulls as $record) {
    if (in_array($record->textField, $fieldValues)) continue;
    $uniques->add($record);
}

$uniqueOrEmpty = $empties->import($uniques);

I edited this code a little and it worked perfectly! Thanks

<?php namespace ProcessWire;

$empties = $pages->findMany("template=record, textField=''");
$fulls = $pages->findMany("template=record, textField!=''");
$uniques = new PageArray();
$fieldValues = [];
foreach ($fulls as $record) {
    if (in_array($record->textField, $fieldValues)) continue;
    $uniques->add($record);
}

$uniqueOrEmpty = $empties->import($uniques);

I just noticed that I forgot to populate $fieldValues array, which effectively removes unique value check. 

You need to add $fieldValues[] = $record->textField at the end of foreach loop
