But you need to turn on "review page" option for this. To do this, you need to edit "view-functions.php" file, try to follow these steps :</p> <p>1. Go to around line 2331 ~ 2445, you'll see these code :</p> <pre><code>$toggle = false; foreach ($entry_details as $data){ if($toggle){ $toggle = false; $row_style = &#39;class=&quot;alt&quot;&#39;; }else{ $toggle = true; $row_style = &#39;&#39;; } $entry_data .= &quot;&lt;tr {$row_style}&gt;\n&quot;; $entry_data .= &quot;&lt;td width=\&quot;40%\&quot;&gt;&lt;strong&gt;{$data[&#39;label&#39;]}&lt;/strong&gt;&lt;/td&gt;\n&quot;; $entry_data .= &quot;&lt;td width=\&quot;60%\&quot;&gt;&quot;.nl2br($data[&#39;value&#39;]).&quot;&lt;/td&gt;\n&quot;; $entry_data .= &quot;&lt;/tr&gt;\n&quot;; }</code></pre> <p>then replace the code with these one </p> <pre><code>$toggle = false; $file_check = false; foreach ($entry_details as $data){ if($toggle){ $toggle = false; $row_style = &#39;class=&quot;alt&quot;&#39;; }else{ $toggle = true; $row_style = &#39;&#39;; } if ($data[&#39;element_type&#39;] == &#39;file&#39;) { if (substr(strip_tags($data[&#39;value&#39;] ),-3) == &#39;jpg&#39;) { $file_check = true; } } $entry_data .= &quot;&lt;tr {$row_style}&gt;\n&quot;; $entry_data .= &quot;&lt;td width=\&quot;40%\&quot;&gt;&lt;strong&gt;{$data[&#39;label&#39;]}&lt;/strong&gt;&lt;/td&gt;\n&quot;; $entry_data .= &quot;&lt;td width=\&quot;60%\&quot;&gt;&quot;.nl2br($data[&#39;value&#39;]).&quot;&lt;/td&gt;\n&quot;; $entry_data .= &quot;&lt;/tr&gt;\n&quot;; } if ($file_check == true) { $on_confirm = &#39;onclick = &quot;return confirm(\&#39;Are you sure you want to upload one image? \&#39;); &quot;&#39;; }</code></pre> <p>2. Go to around line 2400 for this code </p> <pre><code>&lt;input id=&quot;review_submit&quot; class=&quot;button_text&quot; type=&quot;submit&quot; name=&quot;review_submit&quot; value=&quot;{$lang[&#39;submit_button&#39;]}&quot; /&gt;</code></pre> <p>then change it to</p> <pre><code>&lt;input {$on_confirm} id=&quot;review_submit&quot; class=&quot;button_text&quot; type=&quot;submit&quot; name=&quot;review_submit&quot; value=&quot;{$lang[&#39;submit_button&#39;]}&quot; /&gt;</code></pre> <p>That would give a confirmation to "submit" button when one of uploaded file type is "jpg" </p> https://www.machform.com/forums/topic/validate-upload-field#post-9805 Sun, 27 Jun 2010 23:08:04 +0000 drumaboy46 9805@https://www.machform.com/forums/ <p>I just wanted to know if there was a way to validate the upload field for example.</p> <p>If the file ends in .jpg have a message that says, "Are you sure you want to upload one image."</p> <p>Since the upload field does not support multiple files to one field. Currently I have instructed my users to zip the folder in order to send me all there files in one file. </p>
