问题是，当表单被提交时，似乎只有前20行被提交。所有附加的javascript发票行都将被忽略，并且永远不会过帐

      <?php
                for($i=0; $i < 20; $i++){
                    echo '
                    <div class="invoice-line">
                        <div class="prod-id-cell"><input name="rows['.$i.'][id]" type="text" class="prod-id-input">
                            <div class="smart-suggestions">
                                    <!-- RESULT SUGGESTIONS WILL POPULATE HERE -->                              </div>
                        </div>
                        <div class="prod-name-cell">

                                </div>
                        <div class="price-cell"><input name="rows['.$i.'][price]" class="price-input" type="text" /></div>

我已经尝试解决这个问题很长一段时间了，我想知道是否有人可以指导我如何正确地实施这个问题

      <?php
                for($i=0; $i < 20; $i++){
                    echo '
                    <div class="invoice-line">
                        <div class="prod-id-cell"><input name="rows['.$i.'][id]" type="text" class="prod-id-input">
                            <div class="smart-suggestions">
                                    <!-- RESULT SUGGESTIONS WILL POPULATE HERE -->                              </div>
                        </div>
                        <div class="prod-name-cell">
                            <input type="text" name="rows['.$i.'][name]" class="prod-name-input"/>                                  <div class="smart-suggestions">

由于您正在禁用这些值，因此不会发布这些值。具有禁用属性的输入元素不会被发布

      <?php
                for($i=0; $i < 20; $i++){
                    echo '

此外，始终确保元素具有唯一的ID和名称。没有名称的元素不会被发布。

您忘记更改克隆输入的

名称属性。它们将覆盖以前的字段

使用以下命令：

                for($i=0; $i < 20; $i++){
                    echo '

您没有为创建的元素指定新名称。您也在禁用它们

禁用的表单输入将永远不会与表单一起提交。
是否禁用此输入？为什么将其设置为禁用？是什么使它们成为可能？我有javascript来处理禁用的输入字段。当用户在启用的行上方填写时，其下方最近的行（即禁用的行）将自动启用。在动态生成字段时，如何提供唯一ID？@MHZ然后确保动态输入元素具有名称。我列出的两个原因是唯一一个——至少我能想到的——为什么输入元素不能随请求一起提交。@Icarus：另一个可能的原因：它被附加在表单之外。当然，这里的情况似乎不是这样。@Bergi输入字段在我的例子中被追加到表单中，它们应该是这样的。我有javascript来处理禁用的输入字段。当用户在启用的行上方填写时，其下方最近的行（即禁用的行）将自动启用。当动态生成字段时，我如何给出唯一的ID？我可能不使用.replace，而是在javascript中设置一个变量，跟踪其中的行号，然后使用更改名称。避免正则表达式。
