Question

它始终会删除第一个复选框，但不会删除复选框所代表的记录的实际部分。如果我一直点击“保存”，它会从下一个复选框和第一个记录中删除。例如，如果记录是'DMG，SCR，KLS，AST'，当我点击'保存'并刷新页面时，不检查DMG复选框，但记录仍然显示'DMG，SCR，KLS，AST'如果我点击再次，记录变为'SCR，KLS，AST'并且SCR复选框未选中。表单的复选框部分位于底部附近。

谢谢！

我认为问题在于

 <?php if($edit == 1): if(strpos("{$eventType->score_types}", "{$scoreType->name}")): ?> checked<?php endif; endif; ?>>

如果条目位于第一个位置（String中的索引为0），则strpos返回0. PHP假定0等于false，因此第一个与索引0匹配的条目将不会被＆＃34;检查＆＃ 34。

此代码应解决问题（检查false！==）

    <?php if($edit == 1): if(strpos("{$eventType->score_types}", "{$scoreType->name}")!==false): ?> checked<?php endif; endif; ?>>

// Not tested since i dont have PHP installed on this machine. but will try to confirm this asap

<强>更新

Info strpos（...）返回字符串中的索引。计数从0开始，因此您必须明确检查false（=== false）oder（！== false）以确保PHP不会将索引0视为false。这是指向手册（Link）
