php foreach循环生成结果-需要使用选择按钮确定用户选择
我有一个搜索函数，通过GoogleBooksAPI搜索一本书，使用foreach循环以表格格式返回10个结果。几天来，我一直在试图弄清楚如何传递实际的搜索结果，这取决于用户选择了10个搜索结果中的哪一个。我找到了很多答案，但似乎没有一个符合我的具体要求。我想我需要为每个结果动态地创建一个变量，但也许我走错了方向？也许我需要动态地创建表id来选择数据表，但我不知道怎么做。还是动态更改输入选择行的id值php foreach循环生成结果-需要使用选择按钮确定用户选择,php,select,foreach,multiple-results,Php,Select,Foreach,Multiple Results,我有一个搜索函数，通过GoogleBooksAPI搜索一本书，使用foreach循环以表格格式返回10个结果。几天来，我一直在试图弄清楚如何传递实际的搜索结果，这取决于用户选择了10个搜索结果中的哪一个。我找到了很多答案，但似乎没有一个符合我的具体要求。我想我需要为每个结果动态地创建一个变量，但也许我走错了方向？也许我需要动态地创建表id来选择数据表，但我不知道怎么做。还是动态更改输入选择行的id值 <strong><p style="font-size: 16px;

这基本上已经解决了。我可以增加值并输出我想要的精确值。下面我特别指定了2个，第二个结果肯定会进入php文件服务器端。请注意javascript、输入行以及如何将值分配给增量变量的更改 我的最后一个问题是将整数值传递给服务器，因此我不必手动输入2。我想我需要为那个做一条不同的线。也许这会帮助将来找到这条线索的人
