Question

你好，我只想问一下我的项目中有3个表product，color和product_color。我使用insert_batch插入数据库，然后工作正常，当我使用update_batch更新product_color表时遇到一些问题，这是我的示例代码：

数据库：

product:id,name,sku...
color:id,color_name
product_color:id,pro_id,color_id

输入表单：

<?php foreach($colors as $color): ?>
<input type="checkbox" class="form-check-input" name="color[]" value="<?php echo $color->color_id; ?>" <?php foreach ($productcolor as $key => $value){ $array[] = $value->color_id;} if(in_array($color->color_id,$array)) echo 'checked'; else '';  ?>>
 <label class="form-check-label">
<?php echo $color->color_name; ?>
</label>
<?php endforeach; ?>

实际上，我想从product_color表中传递主ID。在这里，我传递color_id。这是我的控制器：

$colorBatch =  array();
foreach ($color as $colorvalue) {               
$colorBatch[] = array(
               'id'=>$id
               'pro_id'    =>$pid,
                'color_id'  => $colorvalue
                );
              }
$this->db->update_batch('product_color', $colorBatch,'pro_id');

其中$ pid包含product_id；

是否可以通过输入表单传递product_color表的主ID或有更好的解决方案来解决此问题。对不起，英语不好。

谢谢

请检查以下代码，因为您的数组结构不正确；

# Build the bigram and trigram models
bigram = gensim.models.Phrases(t_preprocess(dataset.data), min_count=5, threshold=100)
bigram_mod = gensim.models.phrases.Phraser(bigram) 

def make_bigrams(texts):
   return [bigram_mod[doc] for doc in texts]

data_words_bigrams = make_bigrams(t_preprocess(dataset.data))

# Create Dictionary
id2word = corpora.Dictionary(data_words_bigrams)

# Create Corpus
texts = data_words_bigrams

# Term Document Frequency
corpus = [id2word.doc2bow(text) for text in texts]

mallet_path='/home/riteshjain/anaconda3/mallet/mallet2.0.8/bin/mallet' 
ldamallet = gensim.models.wrappers.LdaMallet(mallet_path,corpus=corpus, num_topics=12, id2word=id2word, random_seed = 0)

coherence_model_ldamallet = CoherenceModel(model=ldamallet, texts=texts, dictionary=id2word, coherence='c_v')

a = "When Honda builds a hybrid, you've got to be sure it‚Äôs a marvel. And an Accord Hybrid is when technology surpasses the known and takes a leap of faith into tomorrow. This is the next generation Accord, the ninth generation to be precise."

我该如何解决我的codeigniter批量更新问题？
