我引用了这个问题，但无法从中获取任何可操作的内容以帮助解决我的问题。

PHP INSERT a variable number of records to mysql from a html form

我有一个表单，用于添加无限数量的字段来记录bin权重（jquery）。我无法正确地将数据输入到mysql数据库中。我已经构建了表来建立多对多关系，允许使用唯一的bin id记录bin权重，同时将其重新绑定到接收静态输入的整个作业表中。以下是相关表格。 jobNumber是jobOpen表的主键，它不是AutoIncrementing，而是唯一的。 

    CREATE TABLE IF NOT EXISTS `Production`.`jobCode` (
    `jobCodeID` INT NOT NULL,
    `jobCodeDesc` VARCHAR(45) NOT NULL,
    PRIMARY KEY (`jobCodeID`));

    CREATE TABLE IF NOT EXISTS `Production`.`jobBins` (

public function last_insert_id() {
        return mysql_insert_id();
    }

静态输入可以很好地进入表jobOpen，但binWeights什么都不做。 jobBins表或jobBins_has_jobOpen表中没有填充任何内容。不会抛出任何错误，也不会创建或发布任何值。我确信我遗漏了一些非常简单的东西，但我对JQuery并不是很熟悉，而且我对PHP也不是很了不起......任何帮助都会非常感激。
