Does Eloquent ORM(laravel 5) take care of SQL injection?

由 北慕城南 提交于 2020-01-15 02:40:07
问题 I couldn't find it online, but does Eloquent ORM take care of SQL injection like PDO prepared statements do? 回答1: As per your question all the eloquent queries are taken care of for SQL injection, because they use the PDO driver in core. So you don't have to worry, but the input are stored as they are so you might want to sanitize as per your application's needs (HTML formatting, etc.) 回答2: No framework "takes care of" SQL injection. You take care of SQL injection. A framework may provide

PDO预处理prepare

由 ◇◆丶佛笑我妖孽 提交于 2020-01-15 00:02:30
描述： 预处理语句prepare是pdo提供的一种db操作方式。其语言逻辑与正常的pdo访问相同。但区别于在prepare语句允许用户在【设置sql语句】与【执行sql语句】之间部分进行参数的注入与提取操作，而不是像正常的pdo访问一样直接将参数写死。 （1）prepare()方法和execute()方法 （2）bindValue()方法 （3）bindColumn()方法 正常pdo直接访问：设置sql语句→执行sql语句 预处理访问：设置sql语句→预处理sql语句→处理sql语句中参数→执行sql语句 prepare()方法和execute()方法 prepare()方法为预处理sql语句的方法，能够让pdo预先处理【半成品的】sql语句。并生成一个PDOStatementObject类型的结果。 execute()方法是提供给PDOSO类型对象去执行的【成品】sql语句的方法，并生成一个PDOStatementObject类型的结果。 说明： 交由pdo去prepare预处理的【半成品】sql语句，使用？问号作为占位符，表示待传参的参数。 prepare预处理必须只能处理【半成品】sql语句，如果是完整则需要使用exec方法执行并且会将结果存放到PDOSO对象中。 PDOSO对象在预处理的不同阶段有着不同的含义。 语法： $sql = “insert info

PDO objects across classes

由 爷，独闯天下 提交于 2020-01-14 20:38:09
问题 I'm looking for some feedback on the following: I currently have two classes, which are being used in my PHP application. A database connection class, which is currently using MySQL (but switching to PDO ). Another class (with several functions) which requires database functionality. I'm looking for the best way to design this, I've read up on singletons (with very mixed reviews), read examples where objects were simply declared as new for each method (class functions), and examples where the

Magento loadByAttribute fails on question marks

由 半城伤御伤魂 提交于 2020-01-14 06:24:46
问题 Trying to load a product by it's name ("What are Tests?") fails even though the product exists. $product = Mage::getModel('catalog/product')->loadByAttribute('name', 'What are Tests?'); It works for any other name though. As Magento ultimately goes through PDO, would the "?" in the name be interpreted as a parameter and as I'm not passing any value for it, the ending query would actually be looking for "What are Tests" ... therefore not finding the product? If so, how would I escape it?
