# WordPress Content Encoding Fix - Complete Guide
|
||||
|
||||
## Overview
|
||||
This document explains the encoding issue that was affecting WordPress post ID 112 (Superpowers Plugin article) and provides a permanent solution for preventing similar issues in the future.
|
||||
|
||||
## The Problem
|
||||
|
||||
### Symptoms
|
||||
- Literal `\n` escape sequences appearing as visible text on the webpage
|
||||
- Content displaying incorrectly across the entire article
|
||||
- HTML structure broken due to escaped characters
|
||||
- Poor user experience and unprofessional appearance
|
||||
|
||||
### Root Cause
|
||||
The issue was caused by **PHP-level string escaping** that occurred when content was being inserted into the database. Here's what was happening:
|
||||
|
||||
1. Content with proper newlines was being escaped by PHP functions
|
||||
2. Actual newline characters (`\n`) were converted to literal string `"\\n"`
|
||||
3. These literal strings were stored in the database
|
||||
4. When rendered, the browser displayed the literal `\n` instead of creating line breaks
|
||||
|
||||
### Why This Kept Happening
|
||||
- Using string concatenation or PHP variables to build SQL queries
|
||||
- Functions like `addslashes()` or `mysqli_real_escape_string()` escaping newlines
|
||||
- Not using binary-safe methods for content insertion
|
||||
- Lack of validation after database updates
|
||||
|
||||
## The Solution
|
||||
|
||||
### Permanent Fix Method
|
||||
|
||||
#### Step 1: Create Clean HTML File
|
||||
Create the HTML content with **actual newlines**, not escape sequences:
|
||||
|
||||
```bash
|
||||
cat > /tmp/cleaned_content.html << 'EOF'
|
||||
<!-- HERO SECTION -->
|
||||
|
||||
<section class="hero-section">
|
||||
<div class="hero-content">
|
||||
<h1>Title Here</h1>
|
||||
</div>
|
||||
</section>
|
||||
|
||||
<!-- NEXT SECTION -->
|
||||
<div class="content">
|
||||
<p>Content here...</p>
|
||||
</div>
|
||||
EOF
|
||||
```
|
||||
|
||||
**Critical**: Use actual newlines in the file, NOT `\n` escape sequences.
|
||||
|
||||
#### Step 2: Use MySQL LOAD_FILE() Function
|
||||
Update the WordPress database using binary-safe file loading:
|
||||
|
||||
```bash
|
||||
sudo mysql wordpress -e "UPDATE wp_posts SET post_content = LOAD_FILE('/tmp/cleaned_content.html') WHERE ID = 112;"
|
||||
```
|
||||
|
||||
**Why This Works**:
|
||||
- `LOAD_FILE()` reads the file as binary data
|
||||
- Preserves all characters exactly as they appear in the file
|
||||
- Bypasses PHP escaping entirely
|
||||
- Maintains proper UTF-8MB encoding
|
||||
|
||||
#### Step 3: Verify the Update
|
||||
Always verify the update was successful:
|
||||
|
||||
```bash
|
||||
sudo mysql wordpress --skip-column-names --raw \
|
||||
-e "SELECT post_content FROM wp_posts WHERE ID = 112;" \
|
||||
> /tmp/verify.html
|
||||
|
||||
# Check for literal escape sequences (should return 0)
|
||||
grep -c '\\n' /tmp/verify.html
|
||||
|
||||
# View the content to verify
|
||||
head -50 /tmp/verify.html
|
||||
```
|
||||
|
||||
## Prevention Tools
|
||||
|
||||
### Automated Safe Update Script
|
||||
|
||||
**Location**: `/home/uroma/.claude/skills/ui-ux-pro-max/scripts/wordpress_safe_update.sh`
|
||||
|
||||
**Usage**:
|
||||
```bash
|
||||
./wordpress_safe_update.sh <post_id> <html_file_path>
|
||||
```
|
||||
|
||||
**Features**:
|
||||
1. **Encoding Validation**: Checks file is UTF-8 encoded
|
||||
2. **Escape Sequence Detection**: Scans for literal `\n` sequences
|
||||
3. **Automatic Backup**: Creates timestamped backups before updates
|
||||
4. **Update Verification**: Confirms successful content insertion
|
||||
5. **Error Handling**: Provides clear error messages if something fails
|
||||
|
||||
**Example**:
|
||||
```bash
|
||||
./wordpress_safe_update.sh 112 /tmp/new_article_content.html
|
||||
```
|
||||
|
||||
### Automated Test Suite
|
||||
|
||||
**Location**: `/tmp/encoding_test.sh`
|
||||
|
||||
**Usage**:
|
||||
```bash
|
||||
/tmp/encoding_test.sh
|
||||
```
|
||||
|
||||
**Tests Performed**:
|
||||
1. Literal escape sequence detection
|
||||
2. HTML structure verification
|
||||
3. Article section presence check
|
||||
4. CSS class preservation validation
|
||||
5. Promo text verification
|
||||
6. Discount code presence check
|
||||
|
||||
## Database Configuration
|
||||
|
||||
### Verified Settings
|
||||
```sql
|
||||
-- Database charset
|
||||
SHOW VARIABLES LIKE 'character_set_database';
|
||||
-- Result: utf8mb4
|
||||
|
||||
-- Table charset
|
||||
SHOW CREATE TABLE wp_posts;
|
||||
-- Should show: CHARSET=utf8mb4
|
||||
|
||||
-- Post content field
|
||||
DESCRIBE wp_posts post_content;
|
||||
-- Type: longtext, Collation: utf8mb4_unicode_520_ci
|
||||
```
|
||||
|
||||
### Why utf8mb4 Matters
|
||||
- Supports full Unicode including emojis
|
||||
- Handles 4-byte characters
|
||||
- Prevents character corruption
|
||||
- Industry standard for WordPress
|
||||
|
||||
## Technical Details
|
||||
|
||||
### Before vs After Comparison
|
||||
|
||||
| Aspect | Before | After |
|
||||
|--------|--------|-------|
|
||||
| Content Length | 51,111 chars | 53,256 chars |
|
||||
| Newline Format | Literal `\n` strings | Actual newline chars |
|
||||
| Storage Method | PHP-escaped strings | Binary data |
|
||||
| Display | Visible `\n` text | Proper HTML rendering |
|
||||
| Encoding | Corrupted | Proper UTF-8MB |
|
||||
|
||||
### Content Structure Verified

||||
6. PRICING COMPARISON - Model comparison table
|
||||
7. PROMO SECTION - Z.AI promotional content
|
||||

|
||||
- CSS variables referenced correctly
|
||||
- Inline styles preserved
|
||||
- Responsive design maintained
|
||||
|
||||
## Best Practices for Future Updates
|
||||
|
||||
### DO ✅
|
||||
1. **Always use LOAD_FILE()** for HTML content updates
|
||||
2. **Create HTML files with actual newlines** (not escape sequences)
|
||||
3. **Verify encoding** before database insertion
|
||||
4. **Test content** after updates
|
||||
5. **Use the safe update script** for all content changes
|
||||
6. **Create backups** before any update
|
||||
7. **Check for escape sequences** in source files
|
||||
|
||||
### DON'T ❌
|
||||
1. **Don't use PHP string concatenation** for content building
|
||||
2. **Don't use addslashes()** on HTML content
|
||||
3. **Don't escape newlines** in source files
|
||||
4. **Don't skip verification** after updates
|
||||
5. **Don't assume encoding is correct** without checking
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### If Escape Sequences Appear Again
|
||||
|
||||
**Diagnosis**:
|
||||
```bash
|
||||
# Export content and check
|
||||
sudo mysql wordpress --skip-column-names --raw \
|
||||
-e "SELECT post_content FROM wp_posts WHERE ID = <post_id>;" \
|
||||
> /tmp/check.html
|
||||
|
||||
# Search for escape sequences
|
||||
grep '\\n' /tmp/check.html
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
1. Create cleaned HTML file with proper newlines
|
||||
2. Use LOAD_FILE() to update
|
||||
3. Verify with test suite
|
||||
|
||||
### If Content Appears Corrupted
|
||||
|
||||
**Check Encoding**:
|
||||
```bash
|
||||
file -b --mime-encoding /tmp/your_content.html
|
||||
# Should return: utf-8
|
||||
```
|
||||
|
||||
**Fix Encoding**:
|
||||
```bash
|
||||
iconv -f UTF-8 -t UTF-8 input.html > output.html
|
||||
```
|
||||
|
||||
### If Update Fails
|
||||
|
||||
**Check File Permissions**:
|
||||
```bash
|
||||
ls -l /tmp/your_content.html
|
||||
# Should be readable by MySQL user
|
||||
```
|
||||
|
||||
**Check File Path**:
|
||||
```bash
|
||||
# Use absolute path
|
||||
sudo mysql wordpress -e "SELECT LOAD_FILE('/tmp/content.html');"
|
||||
```
|
||||
|
||||
## Verification Commands
|
||||
|
||||
### Quick Verification
|
||||
```bash
|
||||
# Export and check content
|
||||
sudo mysql wordpress --skip-column-names --raw \
|
||||
-e "SELECT post_content FROM wp_posts WHERE ID = 112;" \
|
||||
| head -20
|
||||
```
|
||||
|
||||
### Full Verification
|
||||
```bash
|
||||
# Run test suite
|
||||
/tmp/encoding_test.sh
|
||||
```
|
||||
|
||||
### Manual Verification
|
||||
```bash
|
||||
# Check for escape sequences
|
||||
sudo mysql wordpress --skip-column-names --raw \
|
||||
-e "SELECT post_content FROM wp_posts WHERE ID = 112;" \
|
||||
| grep -c '\\n'
|
||||
# Should return 0
|
||||
```
|
||||
|
||||
