Question

我有一个填充了数据库中数据的html选择。看起来像这样

#!/bin/bash
sum=0
count=1

read -p "Enter A Grade Point: " grade
while (( $(echo "$grade != 99" | bc) ))
do
    count=$(( count + 1 ))
    sum=$(echo "scale=2;($sum+$grade)" | bc)
    read -p "Enter A Grade Point: " grade
done
    avg=$(echo "scale=2;($sum/$count)" | bc)
         if (( $(echo "$avg 4" | awk '{print ($1 < $2)}') )); then
                echo "Your GPA is $avg"
                echo "This is an B!"
         elif
            (( $(echo "$avg 3" | awk '{print ($1 < $2)}') )); then
                echo "Your GPA is $avg"
                echo "This is a C!"
         elif
            (( $(echo "$avg 2" | awk '{print ($1 < $2)}') )); then
                echo "Your GPA is $avg"
                echo "This is a D!"
         elif
            (( $(echo "$avg 1" | awk '{print ($1 < $2)}') )); then
            echo "Your GPA is $avg"
            echo "This is a F!"
         else
            echo "Your GPA is $avg"
            echo "This is a A!"
         fi
         exit 0

下面我有一个表格，其中填充了数据库中的值。

echo '<select name="client_list">';

  foreach ($htmlselect as $key => $row) {
  echo 
  '<option value='.$row->CUSTOMERCODE.'>'
  .$row->CUSTOMERNAME. '</option>';
  }
 echo '</select>';

现在在这个查询中我想添加到另一个条件，从html选择中获取所选选项值

它看起来像这样

$table = $wpdb->get_results('SELECT STRING, DATE, STRING02  FROM `CUSTOMERFILE` WHERE `code` = 2 AND `status` = 2');

        echo  '<thead ><tr >';
        foreach ($header as $list) {
            echo '<th >' . $list . '</th>';
        }
        echo "<thead></tr>";
  if ( !empty( $table) ) {

             foreach ( $table as $key => $value  ) {
           echo '<tr >';
             foreach ( $value as $a ) {
                if (empty($a)) {
                    # code...
                    echo '<td>NULL</td>';
                } else {
                      echo '<td>' . $a . '</td>';
                      }
                 }   
            echo '</tr>';
          }
      }

如何在查询中传递所选值？

Answer 1

getTagValue(strResponse, "firstname ") public static String getTagValue(String xml, String tagName){ return xml.split("<"+tagName+">")[1].split("</"+tagName+">")[0]; }函数有2个参数，第一个是查询，第二个是输出

$wpdb->get_results()

将选定的选项值传递给mysql查询
