Question

我有一个在线表格，列出了我孩子棒球联赛的投手信息。表格允许输入多个投手（未知数量）。我在循环查看结果时遇到问题，以便通过电子邮件发送给我。

以下是表单中的代码（这是针对pitcher1 - 每个表单最多10个投手）：

<tr bgcolor=#cfcfcf>
<td align=center><b>Team</td><td align=center><b>Pitcher Name</td>
<td align=center><b>Age</td><td align=center><b>Pitches</td></tr>
<tr>
<td><select name="pitcherteam1" size="1">
<option>PLEASE SELECT TEAM
<option>Team 1</option>
<option>Team 2</option>
<option>Team 3</option>
</select></td><td>
<input type=text size=50 name="pitcher1"></td>
<td><select name="pitcherage1" size="1">
<option>AGE
<option>8
<option>9
</select></td>
<td><input type="text" size=3 name="pitcherpitches1"></td></tr>

这是我在php电子邮件功能中的内容：

$size_array = count($_POST['pitcher[]']);
for ($i=0; $i<$size_array; $i++){ 
$message .= <<<MESSAGE

<tr><td>$_POST['pitcherteam'][$i]</td>
<td><b>$_POST['pitcher'][$i]</td>
<td><b>$_POST['pitcherage'][$i]</b></td>
<td><b>$_POST['pitcherteam'][$i]</b></td></tr> 
MESSAGE;
}

我希望遍历表单并仅定位具有投手输入的行（相对于每次回显所有10行并且在非填充字段中具有空白/坏数据）。

Answer 1

更改输入以使用[]语法而不是设置数字：

<tr bgcolor=#cfcfcf>
<td align=center><b>Team</td><td align=center><b>Pitcher Name</td>
<td align=center><b>Age</td><td align=center><b>Pitches</td></tr>
<tr>
<td><select name="pitcherteam[]" size="1">
<option>PLEASE SELECT TEAM
<option>Team 1</option>
<option>Team 2</option>
<option>Team 3</option>
</select></td><td>
<input type=text size=50 name="pitcher[]"></td>
<td><select name="pitcherage[]" size="1">
<option>AGE
<option>8
<option>9
</select></td>
<td><input type="text" size=3 name="pitcherpitches[]"></td></tr>

然后从PHP中删除[]，因为PHP会自动将这些解析为本机数组。如果投手是空白的，也要检查以便忽略该行。

$size_array = count($_POST['pitcher']); // <-- notice there's no []
for ($i=0; $i<$size_array; $i++){ 
    if($_POST['pitcher'][$i] != ''){
       $message .= <<<MESSAGE
        <tr><td>{$_POST['pitcherteam'][$i]}</td>
        <td><b>{$_POST['pitcher'][$i]}</td>
        <td><b>{$_POST['pitcherage'][$i]}</b></td>
        <td><b>{$_POST['pitcherteam'][$i]}</b></td></tr>
MESSAGE;
    }
}

Answer 2

检查是否设置了$ _POST ['pitcher'] [$ i]的值，如果不是，则跳过该消息：

if( !isset($_POST['pitcher'][$i]} ) continue;

或者，对于您的代码：

$size_array = count($_POST['pitcher[]']);
for ($i=0; $i<$size_array; $i++){
  if( !isset($_POST['pitcher'][$i]} ) continue;
  $message .= <<<MESSAGE
     <tr><td>$_POST['pitcherteam'][$i]</td><td><b>$_POST['pitcher'][$i]</td><td><b>$_POST['pitcherage'][$i]</b></td><td><b>$_POST['pitcherteam'][$i]</b></td></tr> 
MESSAGE;
}

这是我从您嵌入的代码中编写的快速脚本。大约一小时前，当我的回答有限时，我看了你的问题，从那以后你似乎已经解决了问题。我没有抛弃这些代码，而是想提供它，以防它或其它人帮助你。

test.php的::

print "<html><head><title>title</title></head><body>";
$size_array = count($_POST['pitcher']); // <-- notice there's no []
for ($i=0; $i<$size_array; $i++){ 
    if($_POST['pitcher'][$i] != ''){
      $team = $_POST['pitcherteam'][$i];
      $pitchername = $_POST['pitchername'][$i];
      $age = $_POST['pitcherage'][$i];
      $pitcherpitches = $_POST['pitcherpitches'][$i];
      if ($pitchername) {
        print "$team, $pitchername, $age, $pitcherpitches<br>";
      }
    }
}

$form_input_row = '<table><tr bgcolor=#cfcfcf><td align=center><b>Team</td><td align=center><b>Pitcher Name</td><td align=center><b>Age</td><td align=center><b>Pitches</td></tr><tr><td><select name="pitcherteam[]" size="1"><option>PLEASE SELECT TEAM<option>Team 1</option><option>Team 2</option><option>Team 3</option></select></td><td><input type=hidden size=50 name="pitcher[]" value="somedata"><input type=text size=50 name="pitchername[]"></td><td><select name="pitcherage[]" size="1"><option>AGE<option>8<option>9</select></td><td><input type="text" size=3 name="pitcherpitches[]"></td></tr></table>';

print "<form method=\"POST\">";
for ($j = 0; $j<6; $j++) {
  print $form_input_row;
}
print "<input type=\"submit\" value=\"submit\">";
print "</form></body></html>";

PHP仅通过电子邮件发送填充值
