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。
