Kesalahan sintaksis WordPress: Pandhuan sing sampurna kanggo ndandani string kutipan tunggal sing ora dikarepke

WordPress Kesalahan PHP bisa uga disebabake dening spasi hantu!

Sing paling ditakuti dening para programer yaiku dudu bug, nanging emosine dimainake dening bug.

Logika sampeyan wrote temenan nggoleki, nanging PHP menehi a syntax errorIku kaya sampeyan telat telung menit kanggo tanggal, lan wong liya nguripake pasuryan lan ngandika "sampeyan ora tresna kula". Sampeyan aran banget salah sing arep uncalan keyboard.

Napa WordPress PHP nglaporake kesalahan?

Pandhuan sing diwenehake dening PHP yaiku:

syntax error, unexpected single-quoted string "wpturbo_handle_upload_convert_...", expecting ")"

Diterjemahake menyang basa manungsa, tegese: Aku ngarep-arep kurung tutup, nanging sampeyan nglebokake karakter aneh ing aku, kanthi watek sing ora bisa diterangake.

Dadi apa masalahe? Iki dudu logika fungsi sampeyan, nanging garis sing katon ora sopan:

add_filter('wp_handle_upload', 'wpturbo_handle_upload_convert_to_webp');

Spasi Roh ing kode

Inti masalah yaiku nalika sampeyan nyalin lan nempel kode, sampeyan nyampur spasi jembar lengkap utawa spasi Zero-jembaré.

Bab-bab kasebut ora katon kanthi mripat langsung ing editor, nanging bakal nggawe PHP edan nalika diurai.

Kayane mangan mie sing enak sak mangkok, nanging ujug-ujug sampeyan nggigit pasir lan pertahanan sampeyan langsung rusak. Iki minangka rasa PHP saiki.

Kepiye cara nulis sing bener?

Apa sampeyan kudu nindakake iku bener banget prasaja. Ganti kabeh spasi hantu kasebut lan tetep spasi setengah jembar sing paling murni.

Kode WordPress sing bener kaya ing ngisor iki:

add_filter('wp_handle_upload', 'wpturbo_handle_upload_convert_to_webp');

function wpturbo_handle_upload_convert_to_webp($upload) {
    if (in_array($upload['type'], ['image/jpeg', 'image/png', 'image/gif'])) {
        $file_path = $upload['file'];
        if (extension_loaded('imagick') || extension_loaded('gd')) {
            $image_editor = wp_get_image_editor($file_path);
            if (!is_wp_error($image_editor)) {
                // Set WebP quality (adjust as needed)
                $quality = 80; // Adjust between 0 (low) to 100 (high)
                $image_editor->set_quality($quality);

                $file_info = pathinfo($file_path);
                $dirname = $file_info['dirname'];
                $filename = $file_info['filename'];
                $def_filename = wp_unique_filename($dirname, $filename . '.webp');
                $new_file_path = $dirname . '/' . $def_filename;

                $saved_image = $image_editor->save($new_file_path, 'image/webp');
                if (!is_wp_error($saved_image) && file_exists($saved_image['path'])) {
                    $upload['file'] = $saved_image['path'];
                    $upload['url']  = str_replace(basename($upload['url']), basename($saved_image['path']), $upload['url']);
                    $upload['type'] = 'image/webp';
                    @unlink($file_path);
                }
            }
        }
    }
    return $upload;
}

Carane supaya iki?

Sampeyan bisa uga mikir, apa sampeyan kudu gugup saben sampeyan nyalin lan nempel? Wangsulane: aja gupuh, nanging kudu pinter.

1. Gunakake editor sing bisa dipercaya, kayata VS Code, sing bisa nyorot karakter aneh kanthi otomatis.
2. Nalika mbukak file, coba simpen ing enkoding UTF-8, sing bisa nyuda risiko "simbol hantu" nganti setengah.
3. Yen sampeyan kuwatir tenan, tempel kode sing curiga menyang alat teks biasa lan ngresiki.

Kaya dene ngumbah sayuran sadurunge mangan panci panas, akeh kacilakan sing bisa dihindari.

Kesimpulan

Kesalahan iki bisa uga katon misterius, nanging logika kasebut jelas banget. Pemrograman kaya nulis puisi; tandha waca lan spasi minangka jiwa irama. Sawijining papan sing ora bener bisa nguncalake kodhe ing irama, kaya tuba sing ora cocog dumadakan muncul ing orkestra.

Nalika nulis kode, kita kudu ngembangake "kebersihan simbol". Mung kanthi nggayuh kasampurnan kanthi rinci, logika bisa mlaku kanthi lancar.FilosofiIng pangertèn, iki uga nguber presisi lan urutan.

kanggo nglumpukake

Ana telung poin utama:

• Kesalahan kasebut dudu masalah logika, nanging ruang hantu.
• Perbaikan sing bener yaiku ngganti karo spasi setengah jembar standar.
• Ngembangake kebersihan kode lan adoh saka karakter sing didhelikake.

Dadi, yen sampeyan nemoni kesalahan sing ora bisa dingerteni, sampeyan bisa uga curiga: Apa ana "hantu" sing ora katon ing kantor? Tumindak, ngresiki, lan kode sampeyan bakal mlaku kanthi lancar.
