Question

我有下面的代码，当在WordPress管理面板中按下按钮时触发该代码。这将打开一个名为'ss-stock-export.csv'的csv文件。

如何在wp-content/uploads/exports/的上传目录中将此文件保存到我的服务器？我尝试使用file_put_contents，但这似乎不正常。 CSV文件显示在正确的位置，但它是空白的。我的$output可能有问题吗？

<?php 
function generate_stock_report_csv() {
    // output headers so that the file is downloaded rather than displayed
    header('Content-Type: text/csv; charset=utf-8');
    // set file name with current date
    header('Content-Disposition: attachment; filename=ss-stock-export.csv');
    // create a file pointer connected to the output stream
    $output = fopen('php://output', 'w');
    // set the column headers for the csv
    $headings = array( 'sku', 'qty', 'is_in_stock' );
    // output the column headings
    fputcsv($output, $headings );
    // get all simple products where stock is managed

    // get all product variations where stock is managed
    $args = array(
        'post_type'         => 'product_variation',
        'post_status'       => 'publish',
        'posts_per_page'    => -1,
        'orderby'           => 'title',
        'order'             => 'ASC',
        'meta_query' => array(
            array(
                'key'       => '_stock',
                'value'     => array('', false, null),
                'compare'   => 'NOT IN'
            )
        )
    );

    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post();
        $product = new WC_Product_Variation( $loop->post->ID );
        $ss_sku = get_post_meta( $product->variation_id, 'ss_sku', true);
        $stock = $product->stock;
        settype($stock, "integer");
        if ($stock > 0){ $stock_status = 1;} else {$stock_status = 0;}
        $row = array( $ss_sku , $product->stock, $stock_status );
        fputcsv($output, $row);
    endwhile;
    $filename = "ss-stock-export.csv"; // Trying to save file in server
    file_put_contents(ABSPATH . "wp-content/uploads/exports/" . $filename, $output);
} ?>

Answer 1

您可以使用ABSPATH中定义的wp-config.php常量将绝对路径传递给file_put_contents。这样，从哪里运行脚本并不重要。

file_put_contents(ABSPATH . "wp-content/uploads/exports/" . $filename, $output);

这就是诀窍

        $csv = "sku,qty,is_in_stock \n";//Column headers
        $args = array(
            'post_type'         => 'product_variation',
            'post_status'       => 'publish',
            'posts_per_page'    => -1,
            'orderby'           => 'title',
            'order'             => 'ASC',
            'meta_query' => array(
                array(
                    'key'       => '_stock',
                    'value'     => array('', false, null),
                    'compare'   => 'NOT IN'
                )
            )
        );

        $loop = new WP_Query( $args );
        while ( $loop->have_posts() ) : $loop->the_post();
            $product = new WC_Product_Variation( $loop->post->ID );
            $ss_sku = get_post_meta( $product->variation_id, 'ss_sku', true);
            $stock = $product->stock;
            settype($stock, "integer");
            if ($stock > 0){ $stock_status = 1;} else {$stock_status = 0;}
            $row = array( $ss_sku , $product->stock, $stock_status );
            $row_array= array($row);
                foreach ($row_array as $record){
                $csv.= $record[0].','.$record[1].','.$record[2]."\n"; //Append data to csv
                }
        endwhile;
        $csv_handler = fopen ('ss-stock-export.csv','w');
        fwrite ($csv_handler,$csv);
        fclose ($csv_handler);
        file_put_contents(ABSPATH . "wp-content/uploads/exports/ss-stock-export.csv", $csv);       
        }
