Laravel 5其中不起作用

Question

I have no idea why my query is suddenly not working (although maybe it was never working to begin with). Is there anything wrong here?

My controller;

$dataset = $postcode_lookup->dataset; // will return "201502_postcode"  

$postcode_extract = new PostcodeExtract;
$postcode_extract = $postcode_extract->setTableByDate($dataset);

foreach ($input as $column => $values) {
    $postcode_extract->orWhere(function ($query) use ($column, $values) {
                            $query->whereIn($column, $values);
                        });
}

/*
*  Temporarily print out the raw SQL...
*/
$sql = str_replace(['%', '?'], ['%%', "'%s'"], $postcode_extract->toSql());
$fullSql = vsprintf($sql, $postcode_extract->getBindings());
print_r($fullSql);

exit;

My model;

<?php namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class PostcodeExtract extends Model {

protected $connection = 'postcodes';

public function setTableByDate($selected_tablename)
{
    $this->table = $selected_tablename;

    // Return $this for method chaining
    return $this;
}

public function getTable()
{
    if (isset($this->table))
        $this->setTableByDate($this->table);

    return $this->table;
}

All that the print out of the raw sql is returning is select * from 201502_postcode and is just ignoring the rest of the query.

This is my $input array;

Array
(
[country] => Array
    (
        [0] => L93000001
        [1] => M83000003
    )

[county] => Array
    (
        [0] => 95
    )
)

orWhere and whereIn is just being ignored it seems..

--- UPDATE ---

I didn't know about orWhereIn. But having tried this;

foreach ($input as $column => $values) {
        $postcode_extract->orWhereIn($column, $values);

        print "<br>";
        print $column;
        print "<br>";
        print_r($values);
        print "<br>";
}

I still get the same result. It's like this loop is being totally ignored - even though I can get these print's/print_r's to work. The raw SQL is still just select * from 201502_postcode .

Answer 1

Try this

$postcode_extract->orWhereIn($column, $values)

Also, if that doesnt work, try making the first one condition a whereIn and the rest a orWhereIn

Answer 2

Oh this is so frustratingly obvious I think I might cry...

foreach ($input as $column => $values) {
        $postcode_extract = $postcode_extract->orWhereIn($column, $values);     
}
