如何通过php和HTML在mysql中只显示非零字段?
上图是mysql数据库中的数据条目 上图是我得到的输出 但我只需要显示非零字段作为输出,这意味着仅从“样本恢复”列显示到“库qc”列 php脚本是如何通过php和HTML在mysql中只显示非零字段?,php,html,mysql,Php,Html,Mysql,上图是mysql数据库中的数据条目 上图是我得到的输出 但我只需要显示非零字段作为输出,这意味着仅从“样本恢复”列显示到“库qc”列 php脚本是 <?php $userinput1 = $_POST['soid']; $servername = "localhost"; $username = "root"; $password = ""; $dbname = "status"; $conn = new mysqli($servername, $username, $passwo
<?php

$result = mysqli_query($conn, "SELECT * FROM $dbname.statusinfo WHERE soid = '$userinput1' ") or die(mysqli_error
($conn));
echo "<p><font size= 4>SO_NUMBER:$userinput1";
echo "<table border='1'>

</tr>";
while($row = mysqli_fetch_assoc($result))
{
echo "<tr>";
echo "<br />";
echo "Department:".$row['dept'] ;
echo "<td>" . $row['samplerecived'] . "</td>";
echo "<td>" . $row['molbioextraction'] . "</td>";
echo "<td>" . $row['molbioextractionqc'] . "</td>";
echo "<td>" . $row['libraryprep'] . "</td>";

?>
在while循环中,对每个字段使用如下方式(对所有字段使用如下方式):
while($row=mysqli\u fetch\u assoc($result))
{
如果($row['samplerecived']==“0000-00-00”)$row['samplerecived']==”;
回声“;
回声“
”;
echo“部门:.”行['dept'];
回显“$row['samplerecived']”;
echo“$row['molboExtraction']”;
echo“$row['MolboExtractionQC']”;
回显“$row['libraryprep']”;
回显“$row['libraryqc']”;
回显“$row['sequencing']”;
回显“$row['datacheck']”;
回显“$row['resquenting']”;
回显“$row['qccheck']”;
回显“$row['analysisstarted']”;
回显“$row['analysiscompleted']”;
回显“$row['report']”;
回显“$row['outbound']”;
回声“;
}
对各个字段使用类型转换操作符int()
$var = (int) $var ? $var : '';
说明:
空日期0000-00-00 00:00:00
始终返回为空的0
在上面的代码中,它将返回0
,因此,它不会显示空白/空日期
只显示一些非零值的日期。如果字段=0000-00-00不回显其日期字段,如何只回显日期字段??应使用if条件或三元运算符!对不起,我没有得到你的分数!!!如果可能,您能简单解释一下吗?如果字段的值为0000-00-00,那么该字段将等于mysqli_查询中查询下面设置的空白(“”),选择soid,dept,if(sampleRecieved='0000-00-00'或sampleRecieved=''',sampleRecieved',,sampleRecieved)作为sampleRecieved,if(molboExtraction='0000-00-00'或molboExtraction='',molboExtraction)作为molboExtraction,如果(MolboExtraction QC='0000-00-00'或MolboExtraction QC='',MolboExtraction QC)作为MolboExtraction QC,如果(LibraryQC='0000-00-00'或LibraryQC=''',LibraryQC)作为LibraryQC,如果(Sequnting='0000-00-00'或Sequnting=''',Sequnting)作为Sequnting,如果(datacheck='0000-00-00'或datacheck='',datacheck作为datacheck作为datacheck,来自$dbname.statusinfo,其中soid='$userinput1'
$var = (int) $var ? $var : '';
