PHP表單不會在數據庫字段中存儲文本$ _POST方法

我正嘗試使用POST方法嘗試向我的數據庫字段中添加文本。我特別提到的數據庫字段叫做ProductVariantHTML。某些原因，它不會將數據發佈到我的數據庫中。

這是我的表單textarea的

<tr> 
    <td><label for="product-variant-html-description">Variant HTML Description:</label></td> 
    <td><textarea id="product-variant-html-description" name="ProductVariantHTML" maxlength=""><?=htmlspecialchars($productVariantHTML)?></textarea></td> 
    <td><span class="input-help"></span></td> 
</tr>

這是ProductVariant類

HTML中某處是否有'

是否所有其他列都得到更新？ – RiggsFolly

您可以發佈整個HTML代碼嗎？ – DamiToma

在與「開頭的SQL語句」 UPDATE product_variant SET SKU ...「：

ProductVariantHTML = $productVariantHTML

應該

ProductVariantHTML = '$productVariantHTML'

我會猜測$ productVariantHTML不是一個數值，也不是inte nded代表表中的另一列。因此它需要引用它。否則，由於您創建了變量「nathan」，因此它會嘗試將ProductVariantHTML列的值設置爲名爲nathan的列的值，因爲SQL解釋器將其視爲字面值，而不是字符串數據。

注意：正如其他人在評論中所說的，你可以通過首先使用適當的參數化查詢來避免這種語法錯誤，而不是脆弱的字符串連接。這樣做還可以更好地防範SQL注入攻擊的實際危險。您的數據可能會被破壞，刪除或泄露給任何使用相對普通技能操作的人。
