Question

我一直在使用代码几个小时，只是看不到我有错误的地方。这是违规代码

$answercreatequery = pg_query("INSERT INTO answer (answerid, questionid, adescription, afilelocation, iscorrect) VALUES( default, '".$thisquestionid."', '".$adescription1."', '".$afilelocation."', '".$iscorrect1."' ");

这是报告的错误

警告：pg_query（）[function.pg-query]：查询失败：错误：语法输入结束时的错误LINE 1：... on，iscorrect）VALUES（默认值为'37'， 'kyfhdkj'，'没'，''^ in /ceri/homes1/m/mtp4/public_html/mmp/Quizmaker/Clientside/questioncreatescript.php 在第167行

我想知道是否有一些我想念的简单的东西？我怀疑是因为$ iscorrect1是boolean类型，我尝试过多次编辑它，但我仍然遇到同样的错误。

您在查询结束时忘记了)：

$answercreatequery = pg_query("INSERT INTO answer (answerid, questionid, adescription, afilelocation, iscorrect) VALUES( default, '".$thisquestionid."', '".$adescription1."', '".$afilelocation."', '".$iscorrect1."' ");
........................................................................................................................................................................................................insert ) here ^

除此之外，您可以简单地省略要使用默认值的列：

$answercreatequery = pg_query("INSERT INTO answer
  (questionid, adescription, afilelocation, iscorrect) VALUES
  ('".$thisquestionid."', '".$adescription1."', '".$afilelocation."', '".$iscorrect1."')");

此外，你应该真的使用pg_query_params（而不是转义或有一个SQL注入漏洞）：

$answercreatequery = pg_query_params('INSERT INTO answer
  (questionid, adescription, afilelocation, iscorrect) VALUES ($1, $2, $3, $4)',
  array($thisquestionid, $adescription1, $afilelocation, $iscorrect1));

这样做也使您的代码更具可读性。
