为什么我的php循环不起作用？

好的我有一个PHP变量$问题，如下所示：

$question['3']['type'] = 'checkbox';
$question['3']['desc'] = 'checkbox question';
$question['3']['deft'] = '1';
$question['3']['opts'] = 'Check Test 1';
$question['3']['opts'] = 'Check Test 2';

我想要做的是这是一个调查问题，其中desc是问题，opts是多个答案。

我目前有这样的陈述：

 if ($type == "checkbox") {
              if (strtolower($deft) == 'y') { $box_value = "1"; $CHECKED = ' CHECKED'; }
                 else { $box_value = "0"; $CHECKED = ''; }
              print "<input type=\"checkbox\" name=\"$key\" value=\"$box_value\"$CHECKED>\n<br>";
         }

它有效，但它不允许我包含一个问题（只有答案）。

我想做这样的事情：

 if ($type == "checkbox") {
            print "<br>\n";
            $i = 1;
            foreach ($opts as $opt_key => $opt_value) {
                if ($deft == $i) {$CHECKED = "checked=\"checked\""; } 
                   else { $CHECKED = ''; }

                print "<input type=\"checkbox\" name=\"$key\" value=\"$opt_value\"$CHECKED> - $opt_value <br>\n";
                $i++;
            }
         }

我收到错误，因为我的代码很糟糕。任何人都可以帮我修复此代码吗？

3 个答案:

答案 0 :(得分：0)

在打印行中$CHECKED之前是否需要空格？

我假设您正在某个地方突破$ {问题}以获取$key，$deft和$opts，因为您没有显示它们的定义位置。 $key应该是$opt_key吗？

答案 1 :(得分：0)

我明白了：

$question['3']['opts'] = 'Check Test 1';
$question['3']['opts'] = 'Check Test 2';

这些是变量：第二个赋值覆盖第一个。

答案 2 :(得分：0)

这有点难，因为我似乎无法找到你的问题，但你的代码看起来像这样：

            foreach ($opts as $opt_key => $opt_value) {
                if ($deft == $i) {$CHECKED = "checked=\"checked\""; } 
                   else { $CHECKED = ''; }

                print "<input type=\"checkbox\" name=\"$key\" value=\"$opt_value\"$CHECKED> - $opt_value <br>\n";
                $i++;
            }

肯定会在html中引起问题。

我建议改写一下（以及报告是否会影响你的错误）。

            foreach ($opts as $opt_key => $opt_value) {
                $CHECKED = $deft == $i ? ' checked="checked"' : '';
                print "<input type=\"checkbox\" name=\"$key\" value=\"$opt_value\"$CHECKED> - $opt_value <br>\n";
                ++$i;
            }

您的代码的问题是生成的标记看起来像name="key"checked="checked"。应该有一个像name="key" checked="checked"

这样的分隔空格
