checked

checked指令专门用来解决复选框和单选的自动选中问题, 可省去多个if判断

<div
    class="form-control"
    php-init="$all_hobby = ["html","css","js","php", "mysql", "linux"]"
    php-init="$user_hobby = ["linux","css","js","php"]">
    技能:
    <label class="checkbox-inline" php-repeat="$all_hobby as $hobby">
        <input type="checkbox" name="hobby" value="{$hobby}" php-checked="in_array($hobby, $user_hobby)" /> {$hobby}
    </label>
</div>
<br />
<div class="form-control" php-init="$user_sex = 1">
    性别: 
    <label class="radio-inline">
        <input type="radio" name="sex" value="0" php-checked="$user_sex === 0"  /> 女
    </label>
    <label class="radio-inline">
        <input type="radio" name="sex" value="1" php-checked="$user_sex === 1"  /> 男
    </label>
</div>

解析后:

<?php
$all_hobby = ["html","css","js","php", "mysql", "linux"];
$user_hobby = ["linux","css","js","php"]; ?>
<div class="form-control">
    技能:
    <?php foreach ($all_hobby as $hobby) { ?>
        <label class="checkbox-inline">
            <?php if (in_array($hobby, $user_hobby)) { ?>
                <input type="checkbox" name="hobby" value="<?php echo $hobby; ?>" checked="checked"  />
            <?php } else { ?>
                <input type="checkbox" name="hobby" value="<?php echo $hobby; ?>" />
            <?php }  echo $hobby; ?>
        </label>
    <?php } ?>
</div>
<br />
<?php $user_sex = 1; ?>
<div class="form-control">
    性别: 
    <label class="radio-inline">
        <?php if ($user_sex === 0) { ?>
            <input type="radio" name="sex" value="0" checked="checked"   />
        <?php } else { ?>
            <input type="radio" name="sex" value="0"  />
        <?php } ?>
        女
    </label>
    <label class="radio-inline">
        <?php if ($user_sex === 1) { ?>
            <input type="radio" name="sex" value="1" checked="checked"   />
        <?php } else { ?>
            <input type="radio" name="sex" value="1"  />
        <?php } ?>
        男

</div>
