基本上，我有一个使用 SQL 来检查是否选择了任何 ID 的 PHP 网页。如果不是，它会自动选择日期为 2015 的所有结果。但是第一个结果总是丢失。通过阅读其他帖子，我只能假设我的 select all $result 从 1 开始，即使表中的数据从 0 开始。要么，要么我的代码的某些部分正在吃掉第一个结果。如有任何帮助，我们将不胜感激。
if (isset($_GET["id"])){$id=$_GET["id"];}else{$id="";}
if ($id==""){
$select ="select * from organicgrants where lastupdated > '2015'";
$result = mysql_query($select);
if (!$result) {
echo("<P>Error performing query: " .
mysql_error() . "</P>");
exit();
}
while ( $row = mysql_fetch_array($result) ) {
$organicgrantsid=$row["organicgrantsid"];

最佳答案
两个 while 循环的目的是什么(除了窃取您的第一个 row – 在内部循环中，您重新分配$row 来自外循环第一次迭代的变量)？移动第一个 while 循环中的所有分配/输出并删除第二个循环(您缺少大括号 {} 所以我猜这是一个内部循环)。
而不是这个:
while ( $row = mysql_fetch_array($result) ) {
$organicgrantsid=$row["organicgrantsid"];
$firstname=$row["teacherfirstname"];
$lastname=$row["teacherlastname"];
$lastupdated=date('F j, Y', strtotime($row["lastupdated"]));
echo ("<p>");
echo("<p><b>Total Applications Displayed: ".mysql_num_rows($result)."</b></p>");
echo ("<table border=\"0\" cellpadding=\"2\" cellspacing=\"0\">");
echo ("<tr bgcolor=\"#cccccc\"><td><Strong>Teacher Name</td><td><Strong>School Name</td><td><Strong>State</td><td><Strong>Grade(s)</td><td><Strong>Submitted Date</td><td><Strong>Status</td></Strong></tr>");
while ( $row = mysql_fetch_array($result) ) {;
$organicgrantsid=$row["organicgrantsid"];
$teacherfirstname=$row["teacherfirstname"];
$teacherlastname=$row["teacherlastname"];
$schoolname=$row["schoolname"];
$schoolstate=$row["schoolstate"];
$gradelevels=$row["gradelevels"];
$lastupdated=$row["lastupdated"];
$grantstatus=$row["grantstatus"];
//$staffawarded=$row["staffawarded"];
//$staffconference=$row["staffconference"];
switch ($grantstatus){
case "":
$grantstatus="Waiting List";
break;
case "0":
$grantstatus="Waiting List";
break;
case "1":
$grantstatus="Awarded";
break;
case "2":
$grantstatus="Not Awarded";
break;
}
$lastupdated=date('F j, Y', strtotime($row["lastupdated"]));
echo ("<tr><td><a href=\"results.php?id=".$organicgrantsid."\">".$teacherfirstname." ".$teacherlastname."</a></td><td>".$schoolname."</td><td>".$schoolstate."</td><td>".$gradelevels."</td><td>(".$lastupdated.")</td><td>".$grantstatus."</td></tr>");
}
echo ("</table>");
}
使用这个:
echo ("<p>");
echo("<p><b>Total Applications Displayed: ".mysql_num_rows($result)."</b></p>");
echo ("<table border=\"0\" cellpadding=\"2\" cellspacing=\"0\">");
echo ("<tr bgcolor=\"#cccccc\"><td><Strong>Teacher Name</td><td><Strong>School Name</td><td><Strong>State</td><td><Strong>Grade(s)</td><td><Strong>Submitted Date</td><td><Strong>Status</td></Strong></tr>");
while ( $row = mysql_fetch_array($result) ) {
$organicgrantsid=$row["organicgrantsid"];
$firstname=$row["teacherfirstname"];
$lastname=$row["teacherlastname"];
$lastupdated=date('F j, Y', strtotime($row["lastupdated"]));
$organicgrantsid=$row["organicgrantsid"];
$teacherfirstname=$row["teacherfirstname"];
$teacherlastname=$row["teacherlastname"];
$schoolname=$row["schoolname"];
$schoolstate=$row["schoolstate"];
$gradelevels=$row["gradelevels"];
$lastupdated=$row["lastupdated"];
$grantstatus=$row["grantstatus"];
//$staffawarded=$row["staffawarded"];
//$staffconference=$row["staffconference"];
switch ($grantstatus){
case "":
$grantstatus="Waiting List";
break;
case "0":
$grantstatus="Waiting List";
break;
case "1":
$grantstatus="Awarded";
break;
case "2":
$grantstatus="Not Awarded";
break;
}
$lastupdated=date('F j, Y', strtotime($row["lastupdated"]));
echo ("<tr><td><a href=\"results.php?id=".$organicgrantsid."\">".$teacherfirstname." ".$teacherlastname."</a></td><td>".$schoolname."</td><td>".$schoolstate."</td><td>".$gradelevels."</td><td>(".$lastupdated.")</td><td>".$grantstatus."</td></tr>");
}
echo ("</table>");
