回声检查选中的复选框

Question

我有一个表单，我可以编辑内容，此时我正在回复输入字段中复选框的值，但我宁愿保留原始复选框并显示哪个已被选中。

     <div class="col-sm-9">
        <label class="checkbox-inline">
            <input type="radio" class="px" name="radiochoice" id="radio11" class="radio" value="No Charge" />
            <span class="lbl">No Charge</span>
        </label>
        <br>
    </div>



    <div class="col-sm-9">
        <label class="checkbox-inline">
            <input type="radio" class="px" name="radiochoice" id="radio7" class="radio" value="185.00"  />
            <span class="lbl">Networking: $185.00</span>
        </label>
        <br>
    </div>

    <div class="col-sm-9">
        <label class="checkbox-inline">
            <input type="radio" class="px" name="radiochoice" id="radio8" class="radio" value="125.00"/>
            <span class="lbl">Mechanical: $125.00</span>
        </label>
        <br>
    </div>

如果我回显它只显示值的值，我该如何显示选中了哪个复选框？

value=<?php echo $radiochoice;?>>

目标：

if ($radiochoice == "No Charge") {          
echo '<div class="col-sm-9">';
echo '<label class="checkbox-inline">';    
echo '<input type="radio" class="px" name="radiochoice" id="radio11" class="radio" value="No Charge" checked/>';
echo '<span class="lbl">No Charge</span>';
echo '</label>';
echo '<br>';
echo '</div>';

echo '<div class="col-sm-9">';
echo '<label class="checkbox-inline">';
echo '<input type="radio" class="px" name="radiochoice" id="radio7" class="radio" value="185.00"  />';
echo '<span class="lbl">Networking: $185.00</span>';
echo '</label>';
echo '<br>';
echo '</div>';

echo '<div class="col-sm-9">';
echo '<label class="checkbox-inline">';
echo '<input type="radio" class="px" name="radiochoice" id="radio8" class="radio" value="125.00"   />';
echo '<span class="lbl">Mechanical: $125.00</span>';
echo '</label>';
echo '<br>';
echo '</div>';

echo '<div class="col-sm-9">';
echo '<label class="checkbox-inline">';
echo '<input type="radio" class="px" name="radiochoice" id="radio9" class="radio" value="59.00" />';
echo '<span class="lbl">Remote half: $59.00</span>';
echo '</label>';
echo '<br>';
echo '</div>';

echo '<div class="col-sm-9">';
echo '<label class="checkbox-inline">';
echo '<input type="radio" class="px" name="radiochoice" id="radio10" class="radio" value="89.00"   />';
echo '<span class="lbl">Remote 1 HR: $89.00</span>';
echo '</label>';
echo '<br>';
echo '</div>';


} elseif ($answer == 185.00) {

ETC ETC

Answer 1

虽然你可以添加的每个输入都不优雅

defer

相应地更改值，它可能是$ _GET，具体取决于表单操作
