我遵循PHP代码:
<?php
$rebate_no = 2;
echo "<table id='blacklistgrid_$rebate_no' class='table table-bordered table-hover table-striped blacklistgrid'>
<tr id='reb$rebate_no_1'>
<td>
<div class='btn-group'>
<select name='product_id_$rebate_no[1]' id='product_id_$rebate_no_1' class='form-control prod_list'>
<option value='1'>Alabama</option>
<option value='2'>Alaska</option>
<option value='3'>Arizona</option>
<option value='4'>Arkansas</option>
<option value='5'>California</option>
</select>
</div>
</td>
</tr>
</table>";
?>
在上面的代码中,我遇到了以下几行连接变量和字符串的问题:
<tr id='reb$rebate_no_1'>
<select name='product_id_$rebate_no[1]' id='product_id_$rebate_no_1' class='form-control prod_list'>
我尝试了以下技巧,但它对我不起作用。
<tr id='reb'.$rebate_no.'_1'>
<select name='product_id_$rebate_no[1]' id='product_id_'.$rebate_no.'_1' class='form-control prod_list'>
如果我签入HTML源代码,我将关注HTML:
<tr id="reb" .2.'_1'="">
<select id="product_id_" class="form-control prod_list" .2.'_1'="" name="product_id_">
实际上我希望HTML符合以下格式:
<tr id='reb2_1'>
<select name='product_id_2[1]' id='product_id_2_1' class='form-control prod_list'>
如何实现这一目标?提前谢谢。

字符串连接
<?php
$rebate_no = 2;
echo "<table id='blacklistgrid_".$rebate_no."' class='table table-bordered table-hover table-striped blacklistgrid'>
<tr id='reb".$rebate_no_1."'>
<td>
<div class='btn-group'>
<select name='product_id_".$rebate_no[1]." id='product_id_".$rebate_no_1."' class='form-control prod_list'>
<option value='1'>Alabama</option>
<option value='2'>Alaska</option>
<option value='3'>Arizona</option>
<option value='4'>Arkansas</option>
<option value='5'>California</option>
</select>
</div>
</td>
</tr>
</table>";
?>
或强> 如果你想使用Zend规范
<?php
$rebate_no = 2;
echo "<table id='blacklistgrid_{$rebate_no}' class='table table-bordered table-hover table-striped blacklistgrid'>
<tr id='reb{$rebate_no_1}'>
<td>
<div class='btn-group'>
<select name='product_id_{$rebate_no[1]} id='product_id_{$rebate_no_1}' class='form-control prod_list'>
<option value='1'>Alabama</option>
<option value='2'>Alaska</option>
<option value='3'>Arizona</option>
<option value='4'>Arkansas</option>
<option value='5'>California</option>
</select>
</div>
</td>
</tr>
</table>";

你从双引号开始,所以你可以这样做:
<tr id='reb".$rebate_no."_1'>
或在变量周围使用花括号{}
:
<tr id='reb{$rebate_no}_1'>
两者都有效。
答案 2 :(得分:1)
试试这个:
<tr id='re'".$rebate_no."_1'>
<select name='product_id_$rebate_no[1]' id='product_id_".$rebate_no."_1' class='form-control prod_list'>
当你在串联字符串时,你需要使用双引号,因为你用双引号开始字符串。

问题在于$rebate_no[1]
。你可以将它的值存储到常规变量中,将值附加到字符串中,如下所示,或者用大括号括起来,如{$rebate_no[1]}
echo "<table id='blacklistgrid_$rebate_no' class='table table-bordered table-hover table-striped blacklistgrid'>
<tr id='reb$rebate_no_1'>
<td>
<div class='btn-group'>
<select name='product_id_" . $rebate_no[1] . "' id='product_id_$rebate_no_1' class='form-control prod_list'>
<option value='1'>Alabama</option>
<option value='2'>Alaska</option>
<option value='3'>Arizona</option>
<option value='4'>Arkansas</option>
<option value='5'>California</option>
</select>
</div>
</td>
</tr>
</table>";

你弄错了。
而不是
<tr id='reb'.$rebate_no.'_1'>
做
<tr id='reb".$rebate_no."_1'>
答案 5 :(得分:1)
最简单的方法是使用(“”)双引号而不是(''),而不会使它变得复杂。
<tr id="reb$rebate_no_1">
<select name="product_id_$rebate_no[1]" id="product_id_$rebate_no_1" class='form-control prod_list'>
而不是
<tr id='reb$rebate_no_1'>
<select name='product_id_$rebate_no[1]' id='product_id_$rebate_no_1' class='form-control prod_list'>
